I need some help. I wanted to play ranked battles but when I pressed the battle option, it told me to make a username even though I already made one which is PumpkinProGames. I typed my username and it said at it was invalid even though it had 15 characters only. I still have all my cards and all my progress. Is there a solution to the problem of my game?
