LOZ: Twilight Princess Demo (sort of)

Okay, I got the game LOZ:TP for Wii. It was $5, so I kinda knew something was wrong with the disc. The game fully works up to the point where Link becomes the wolf and you dig your way out from the prison. The game stops loading.

I'll sell it for $5 because for a demo, it's long. Also, if you manage to get the scratches off with toothpaste or whatever, It beats buying a used copy for around $30.

Maybe you should check this out as I'm sure the board police will come flaming you soon.

Sorry if I sound like an idiot, but, what did I do? Is it because of me making 2 threads here at once or for selling a game demo? I didn't see anything in there about not selling a demo.
