Hello! I have a problem with my wallet.dat. I had a back-up wallet.dat from 6 months ago and It's not working when replaced with original wallet.dat when I installed the new XBY-QT I get the error Warning: error reading wallet.dat! All keys read correctly, but transaction data or address book entries might be missing or incorrect. I looked around on google but there is not much info how to fix it. The Wallet is fully sync. I don’t have my private key on paper please help me!
