Topic: Help: Bitcoin-QT won't start up (Read 2040 times)
Alright, I've reinstalled it. Seems to work fine. When the blocks are updated, I'll restart it and post if I have more problems...
download new version of bitcoinQT
Don't forget to backup your wallet during the imstallation though. 
Second ASanerWorld's advice. I would suggest these steps:
1. Back up your wallet: In Windows Explorer, go to %APPDATA%\Roaming\Bitcoin. Copy the file Wallet.dat to some other safe location.
2. Uninstall Bitcoin-QT through the Control Panel.
3. Go back to %APPDATA%\Roaming\Bitcoin. If there's anything still in there, delete it all.
4. Download the latest Bitcoin-QT and reinstall.
5. Import your wallet from your backup: go once more to %APPDATA%\Roaming\Bitcoin, and copy your backup you created in step 1 into this folder.

I'm a linux nerd, so take my advice with a grain or two of salt, but my first suggestion would be to copy the wallet.dat file someplace safe and then re-install the program. That's how I handled moving my wallet from a no-longer-used partition on my PC to a new location. Once it finished syncing, all was fine. Windows folks can verify if this will work, I suspect.
Had it been working before or is this the first time?
This is the first time. I was able to run it yesterday... really, the only other time I ran it.

When I attempt to open, the splash screen shows and an error pops up:
"Error opening block database.
Do you want to rebuild the block database now?"
OK and Abort buttons show.
Pressing OK brings up this error:
"Error opening block database"
With only an OK button.
These errors pop up as Windows dialogue boxes.
