11DbException

[curmudgeon]

My Windows 7 machine recently crashed and after I restarted I now get this error when Bitcoin starts up:

EXCEPTION: 11DbException       
Db::open: Invalid argument       
C:\Program Files (x86)\Bitcoin\bitcoin.exe in CMyApp::OnUnhandledException()   

Of course my wallet file was not backed-up, but I do have the address.  Is there any way to recover the coins or am I SoL? 

Thanks

I've run into the same problem. Backup your wallet.dat if you haven't already. Try removing the "old" wallet and try again. If that doesn't work it means it is the database. If it is the database, you would need to remove the database folder and blk*.dat files and redownload the chain.

I haven't been able to figure it out yet. Trying to narrow it down myself.
