Copy the contents of the CMD window down to a text file. If you have ONLY received coins on a couple of address, find them and copy the data for the 'sec' column (that you censored fortunately).  Just make a blockchain.info wallet, and import those privatekeys to the wallet (choose Sipa wallet format or Base54, I've forgotten that). You'll see the balance there. Afterwards, just get a new wallet file by deleting the old wallet (BACKUP FIRST) and restarting the bitcoin client. Try sending test amounts of coins to it (faucet?) ,and if it works just send the coins back to it. You can also try other alternative clients like Electrum or Armory.

If blockchain.info shows that the receiving address has the coins, and you have the wallet to that address, your coins is safe.If everything fails, you can use pywallet at https://bitcointalk.org/index.php?topic=34028.0 to extract your privatekeys. Alternatively, you can use the 'bitcoind dumpprivkey' command on CMD at the Bitcoin Client directory (Assuming windows) to get the privatekeys. Import the keys to Blockchain.info's online wallet and send the coins to a new, working wallet.dat.

edit: removed an address from my previous post.

If you moved between XP and Windows Vista/Wiindows 7, know that there is a different directory used.

Also, always close the client before backing up or restoring the wallet.dat.

Stop bitcoin/d
Remove any database/log* files from your bitcoin data directory
