Quit BiblePay QT Wallet

Backup your wallet.dat - erase everything except for wallet.dat and biblepay.conf

Inside biblepay.conf make sure you have at least:

So, inside %appdata%/BiblePayCore should only be those two files.

Restart QT wallet

If you see that your total balance is incorrect, wait until you are fully synced.

Then do a Tools, Wallet Repair, zapwallettxes=1
