So about a week ago I was doing pretty good at the game and I was gaining a decent amount of pp and clearing a lot of low 4 star songs without much trouble. I started having problems with my mouse grip which I think I've fixed and either yesterday or 2 days ago I cleared a couple 4 star maps but now I can hardly clear them at all. I've managed to clear about two 4 star maps just barely in around the past hour. I just can't play them at all anymore. Any suggestions on what to do?
