There may be something that can be done to get it to work.

It's kicked me out 4 times now!  I've restarted and it will say scanning for about 5 minutes the  say that it has quit working.
That's not good.  And unfortunately we've moved beyond my ability to help you.  I'm not sure why Bitcoin-Qt won't load up the wallet that you backed up on 11/23.  There may be something that can be done to get it to work.  If not then there is a tool (pywallet) for dumping out the contents of the wallet so that you can load them into a new wallet, but I'm not familiar with how to use that tool.

Hopefully you will get some assistance from someone with a bit more expertise than me.  As long as you have that wallet.dat, there is a pretty good chance that you'll be able to recover the coins with the right help, so be careful not to lose it.  I assume that right now you have 2 copies (one on the flashdrive and one in %appdata%/roaming/bitcoin).

So it could take quite a while? 
As long as your wallet.dat file is not damaged, you should be ok.  It may take a while.  Try to be patient at this point.  If after an hour it is still "rescanning" you can try asking for advice here in the forum.  I may not be around at that time, so you may need to get assistance from someone else if the "rescanning" doesn't complete successfully.

i tried what you said and the wallet says "rescanning" for a while now.....
That is a good sign.  That means that is loaded up with a different wallet.dat than before.  It has to scan the blockchain that it has downloaded so far so it can determine what coins for the addresses in that wallet are in the downloaded portion of the blockchain.

wallet
wallet1

i saw your post but both the wallet1 11/23 and wallet 11/26 are in the appdata-->roaming-->bitcoin folder
This is what is causing your problem.
The wallet cannot be named wallet1.  If it is then Bitcoin-Qt won't see it.  Even if it is in the directory, Bitcoin-Qt won't care.  It won't even look at a file named wallet1  It will ONLY use a file named wallet.

Stop Bitcoin-Qt
Wait for it to shut down all the way
Change the name of the "wallet" file (the one from 11/26) to OLDwallet
Change the name of the "wallet1" file (the one from 11/23) to wallet
Start Bitcoin-Qt
Check and see if your addresses are there

. . . it has both wallet.dat files, the one that i backed up created on 11/23 and another one that says modified 11/26. . .
This is what I suspected.  Are they both the EXACT SAME filename?  Same capitalization, same spelling, etc?
Bitcoin-Qt is looking for a very specific filename for the wallet.dat file.  The way the 11/26 filename looks... That is probably the wallet.dat that you currently see in Bitcoin-Qt.  It is the filename that Bitcoin-Qt looks for.  If there are ANY differences in the filename of the 11/23 file, then that is your problem, and it will be easy to fix.

Assuming that you see a difference in the filename...
 
  • Stop the Bitcoin-Qt program, and wait for it to fully shut down
  • Change the name of the 11/26 file to 2012-11-26.wallet.dat
  • Change the name of the 11/23 file to exactly what the 11/26 filename used to be
  • Start Bitcoin-Qt back up
  • Confirm that your bitcoin address is there now

If you don't see any differences in the filename, then do not follow those instructions, we need to continue to figure out what happened before we make any changes.

I got my computer back and running. So what is your advice?  What should I do next?
It sounds like the flashdrive should have a good copy of your wallet.dat based on the events you've described.  Now we need to figure out what happened when you copied it off the flashdrive into the %appdata%/roaming/bitcoin directory...

When you use the "Backup Wallet" option in Bitcoin-Qt, I think you get a "Save As" box, right?  Which means you get to choose the name of the wallet file when you save it?  I'm not much of a Windows user, but isn't Windows case sensitive on filenames?  (meaning that as far as Windows is concerned, WALLET.DAT and wallet.dat are 2 different files?)

It is possible that when you copied the file to the %appdata%/roaming/bitcoin directory, you used a filename that Bitcoin-Qt didn't recognize.

Can you look at your %appdata%/roaming/bitcoin directory and list all the filenames that are in there right now?

Ok so first of all my hard drive crashed two weeks ago. Someone restored it and I had all old files on .old file. I could still get to my wallet. I decided to buy some coins Friday. When I got home I checked to see if they posted, Rey had not so I was looking around and saw the option to backup wallet. At this time I backed it up on a flash drive. Saturday night I left my CPU on because the blockchain was about 40k behind(I'm guessing from being down 2 weeks). Sunday morning my wallet was stuck on "loading blockchain index". I joined this forum and the advice I got was to delete everything from the bitcoin folder and transfer the .dat file I had on flashdrive bak to the bitcoin folder. I opened my wallet and it seemed to work (I was unable to open before). Then I realized that addressed weren't there. Now I think my hd failed again because it says "startup repair", your computer was unable to start. I'm typing this on iPhone.

. . . what do I do next what do I need to delete from the btc folder now and replace?
Hang on. Lets not rush into deleting stuff and moving stuff around if you don't understand what you are doing.  That is how you got into the situation in the first place.  Lets get a better understanding of what you have and where your addresses are...

I backed up the flash drives After my last transaction because the blocks chain was taking so long that I thought there could possibly be a problem so I backed up my DAT file. Okay so earlier the wallet had a problem loading the block chain index and i talked to somebody on the forum that told me type in % app data % then go to the bitcoin folder and delete everything in it then take the .DAT file off my flash drive and copy it over there . . .
Ok, this is the part that has me confused.  If you didn't know where your %appdata% folder was then how did you back it up to the flashdrive?  What is on the flashdrive? How did it get there?  You say you "backed up the flash drives", but I don't know what you mean by this.  What did you copy to the flashdrive, where did you copy it from?

So, when did you put the wallet.dat file onto the flashdrive?  Was that something you did in the past to backup your wallet?  Days ago? Weeks ago? Months? Years?  Was it something that you just put onto the flashdrive right before you put stuff into the trashbin?  Did you do anything before putting stuff into the trashbin? (such as re-installing bitcoin-qt, or deleteing files from appdata?)

I'm trying to figure out why you thought the wallet.dat you are using should have your addresses, and why it doesn't.  It seems like you must have mixed up some steps in your process.

also what is the private key associated with the address?  how do i find this?
The private key is what allows you (or anyone) to spend the bitcoin that is associated with the bitcoin address.  Whoever has the private key can spend the coin, so you don't want to leave that where a thief or hacker can get at it.  The bitcoin-qt program hides the private key in the wallet.dat file.  It doesn't show it to you, but when you send coins the program uses the private key that is stored in wallet.dat to sign the transactions so that they will be considered valid transactions on the bitcoin network.  Once you get your bitcoin-qt program running with the correct addresses, I'll give you instructions on how you can get access to your private keys so that you can keep them safe on a piece of paper or something if you want.  That way if you ever lose your wallet.dat (and all backups), you can still get access to your bitcoins.

For now, since you don't have the private keys stored separately anywhere lets focus on getting your proper bitcoin addresses back.
