OK I had a system lock-up necessitating a hard reset. Now Bitcoin won't start:
EXCEPTION: 22DbRunRecoveryException
DbEnv::open: DB_RUNRECOVERY: Fatal error, run database recovery
bitcoin in AppInit()
Can I just delete and re-run the script? There was nothing in the /bitcoin folder I needed. In fact I don't think it ever created a wallet.dat file
If you delete wallet.dat you lose all your bitcoins. You can delete everything in .bitcoin but NOT Wallet.dat and Bitcoin.conf
