Error:
Runaway exception

CDB: Error -30974, can't open databaseI suspect you have no previous backup, from when it was working......
Before trying to send coins, run the command dumpprivkey
walletaddress for each address you have in your wallet.
Copy these private keys in a safe place and then insert them in a new, clean and freshly installed wallet.
This will get you your coins into the new wallet.
