How do I fix my Desperate Housewives game?

I've had this game since it first came out and recently I decided I wanted to play it again. I've gotten to episode 6 and after that it will not continue. Each time I try to reload the game it has stopped working. I've already uninstalled the game twice and each time it will not continue any further past that one part in the game. Can anyone help me?

Or to get rid of scratces yourself rub enough toothpast to cover the bottom of the disk and gentally wash it off with and diet soda. and if that dosnt work the it may be a manufacturing problem, like a glitch in the game.
