i removed peers.dat file and it worked fine after that
and do i have to change my address , or i can continue using old address that starts with 1
and where can i see my added address in wallet
As I remember BTX addresses begun from 1xxx no longer support since Autumn'2018
But private keys are remained the same.
So to get access to the funds it needs to make the following
1. dump private keys from old version wallet (you do not need Internet connection \ wallet sync for this procedure)
2. import private keys to the new wallet
