A fatal error occurred.......

[meanig]

Need some help guys. I loaded an old wallet into my client and tried to send some coins to a new address. I got the following error message

Code:

A fatal error occurred. Bitcoin can no longer continue safely and will quit.

EXCEPTION: St13runtime_error
CWallet::GenerateNewKey() :AddKey failed
C:\Program Files (X86)\Bitcoin\bitcoin-qt.exe in Runaway exception

I'm running version 0.8. The old wallet was last opened in summer 2012 in probably 0.6.

Thanks

Adding to the intrigue it gives me another error on startup

Code:

System error: CDB() : can't open database wallet.dat, error -30974

I'm getting the feeling my wallet.dat is fooked

A little bit of digging shows the -30974 error has happened to other people too. The advice given was to use pywallet to extract the keys but there was never a follow up saying it worked.

Has anyone recovered from this error using pywallet?
