I downloaded this game a while ago now and for some reason every so often the microphone won't register, I'm on an iMac and I've been using video game microphones like the ones with Rock Band/Guitar Hero and other ones like that, I always plug them in before starting the game but I get an error message saying that my microphone hasn't been assigned to Player 1, I've tried getting it to work through the Record section but the microphone doesn't even show up there right now.
