What about if I never had B3 wallet and want to install it now. Do I have to install the latest version and that's it? Or do I have to configure something?
i've installed the wallet on a clean pc and it was downloading the wrong blockchain from one or more peers.
So i had to download the blockchain manually (only once) and place it in the correct appdata folder. The wallet should work once you have done this.
I think this error i due to people that are still running an old wallet and are broadcasting the wrong chain.
