So I had some BTC on an older Windows computer with an old version of the BTC client, 0.3.x.    It was crashing on me after a minute or so of being open, and I kept restarting it and finally sent all my BTC to an address of a wallet I had stored on another computer

I closed the bitcoin client that was buggy/crashing on me right after sending the coins.   I backed up the wallet.dat and moved it to a computer with a working (latest) version of the bitcoin client.  It was fully synced up with the blockchain before overwriting the wallet.dat.  When I launched the client it showed my transaction in the tx list but it was 0/confirmed, and still is (this is about a week after sending the coins).  The balance is 0 so the coins are out there 'in limbo' and blockchain.info doensn't have any record of the transaction and they never arrived at the destination

what do?
