Yesterday it was working and today it appeared 0 blocks, I backed it up and tried to reinstall. The account disappeared and even with the backup no longer appeared. I created a new account and tried to restore the backup but it did not work. I rebooted the windows, closed and opened several times and the account never appeared again. I checked the Dubaicoin directory that is inside the users directory and everything was ok, but the account did not appear at all. Actually the wallet is very unstable and from the beginning I realized that it is very poorly made. I will leave what is minted on coinpayments in the hope that a new wallet will emerge.
