Guys,
I really need help on how to recover my balance:
So i updated to the latest version and my balance is showing 0 now after being synced or reindexing.
i used my backup wallet.dat and writed over the new wallet.dat. and Loaded BiblePay again and reindex it. Tools >> Wallet Repair >> Rebuild index and still nothing
I also i noticed that my wallet adress has changed.
The last 3 versions were mandatories, but did not create a breaking change for your prior balance.
The only way you could have lost coins is either: a) you lost your wallet, or b) you mined on a fork.
Please tell us, did you obtain this balance through mining between 1.0.6.5 and 1.0.7.1 or did you have it prior?
If your address changed you probably restored the wrong wallet. You will have to find the original wallet or keys and restore from that backup.
