The wallet stopped sending coins, everytime I try to send coins I just get

error: {"code":-4,"message":"Error: The transaction was rejected.  This might happen if some of the coins in your wallet were already spent, such as if you used a copy of wallet.dat and coins were spent in the copy but not marked as spent here."}


Pool is now closed.

I'll try to reindex the wallet by restoring from privkey now. A simple rescan, rehash and a repair wallet didn't help.
