Anyway I'm using the 2.1.0 version..
I tried also to install btc2 wallet on my other pc hoping that the problem is in my personal PC but the problem occur, I am willing to give you my wallet.dat @jacklezz for you to test it, and one of my mind to solve it is to give you the wallet.dat then send it to me my btc2 inside of it.. I have 5.8 to 6 plus BTC2 inside.
I recommend you to do one of the following:
A) Use one of the older wallet.dat files from your previous backups folder if you have it.
B) Use Tools - Wallet repair - Salvage wallet. then import the private keys from it after generating a new wallet.dat (moving the corrupted wallet.dat somewhere else will generate a new wallet.dat)
.... Or if you already have the private key of your BTC2 address, then you can just do step B) without using the Salvage wallet button.
There is no way of doing that, because after loading the wallet it pop up the error message, I have my wallet.dat keep on my folder, but when I tried to fresh install and synced, then copied my wallet.dat, when I open again the wallet it's loading but when reached the 50% loading, the error pop up again! I think the problem is in my wallet.dat, how that will happen? That's why I just want to send my wallet.dat to your team and fix it, then send it to me... Is that possible? Kindly need your help..
