I downloaded Psychonauts from the Xbox Originals part of the marketplace. I've found that when I try to load a game, or after a cut scene I have no ability to control the game. No matter what I do, what button i press, nothing will work. I've even deleted the game off of my hard drive and redownloaded it, but the problem persists. Any help/tips would be greatly appreciated. Thanks =]

remove all devices from controller ports and you will be golden.
