So, I've been playing MH:W lately, and my xbox controller has been treating me grandly. Up until tonight. I plug in the controller, and suddenly the A button doesn't work. After some testing, I realize that I can hit the A button once if I alt tab from my game and back in, but after the one press, it stops working again. This is consistent across any game I try on this controller. It's an odd issue that googling has done nothing to solve. Any ideas?
