user6446: Running Windows 7;
I'm not really sure what is going on. The wallet has stolen my BTC.
The wallet never synchronizes, it never finishes. If I leave it on all day -I will come home to see it crashed.
The application is also not visible from anywhere except possibly from Task Manager. When I try to start it.. it says: 
cannot obtain a lock on data directory ... Bitcoin is probably already running.
My goal here is to get the bitcoins that I have and move them back to the account I have with the vendor. Then I will purge my system of this so called "program" and never use it again.
Additional information: Bitcoin Wallet version 0.5.0.1
This is old -can I upgrade without losing my secure key? WHERE IS MY WALLET.DAT FILE? I CAN'T FIND IT.

ANY HELP IS GOOD. 

user1420: Two actions here:

Back up your wallet.dat file

You will most likely find it here, based on these instructions:
https://en.bitcoin.it/wiki/Securing_your_wallet#Windows_2

C:\Documents and Settings\YourUserName\Application data\Bitcoin
  (Windows XP)
C:\Users\YourUserName\Appdata\Roaming\Bitcoin (Windows Vista and 7)


Update your bitcoin-qt instance to the latest version:

user214: In case everything else fails, you can import your wallet into blockchain.info. See e.g. How to import your Bitcoin wallet.dat into Blockchain.info by Damien P for more information.
