I bought this game an hour ago. I'm trying to play single player but everytime I pick mime toss, pain bowling, spank the monkey and other game modes, the game turns into split screen. I've tried a lot and can't figure out how to stop the game from making me choose 2 characters and going into splitscreen mode... The only thing that doesn't put me into splitscreen is paindemonium..

Can anybody help me out with this please?
