ok file did not work... I am going to try and use the hex editor to find the private keys. My wallet is encrypted with a passphrase (password) hopefully this will not be a huge problem but I do know it.  Basically I had a large transfer recently which mainly is the balance of the account.  Am I looking for a public key which follows by a private key eventually?  If I know the address of the transfer does that help?  Do I need only one private key to recover the lost bitcoins?    Any help is appreciated.
