I have a copy of New Super Mario Bros Wii, and everytime I try to play it, right after I hit "start" it says something like "Unable to read." We brought it GameStop, where we bought it, and the guy, clearly not trying to help us, says it's scratched. I always kept it in the box or in the Wii, and its never touched the floor or anything. When you look at it you can't see any scratches. Any help?
