i recently used the scotch guard lens cleaner to clean the dvd drive on my x-box. the product is a cd with little brushes attatched which i assume cleans the lens. however since using the product the x-box refuses to read any game disks and only one or two dvd's. The x-box was working fine before i used the cleaner. Any ideas as to what has happened. It looks like i will have to buy a new x-box.
