I had an Xbox about 2 years ago and started playing again. I've downloaded a lot of the great games I used to love off the marketplace again, like Geometry wars for example and they work fine.
I recently had the urge to play Grand Theft Auto: San Andreas I downloaded and updated it. It claims that the "disc" is dirty or broken... Which leaves me to ask the question... How would I go about cleaning my "disc" this is clearly an error of some sort and I was wondering if it could be fixed somehow.
