I used the bitcoin-qt client for OSX. I transfered 4BTC into my wallet and soon after I did a backup. Then I encrypted the wallet, after the encryption the coins were gone. I tried reverting to the backup and they aren't there either. Should I kiss my 4BTC goodbye or is there something I can do to get them back?
Thanks!

Chances are you are still happily downloading the blocks, it is "syncing" right?
Gabi is most likely correct.
1) When you view the "Receive coins" tab in the client, do you still see the address listed there that you sent the 4 BTC to?
2) Have you ever sent any of those 4 BTC (even as little as 0.00000001 BTC) from that client to anywhere at all?
If the answer to the first question is "Yes"
and the answer to the second question is "No", then you probably jsut have to wait for it to finish synchronizing with the bitcoin network (depending on your computer this could take anywhere from a few hours to a few weeks).
If
either the answer to the first question is "No"
or the second question is "Yes", then there could be other issues that you might need some assistance with.
