So I downloaded GTA San Andreas using xbox live a few weeks ago, and I've been getting the error (paraphrasing) "The disc you're using may be dirty or damaged." Obviously, there is no disc. The error always comes up in the same in-game locations. The weird thing is that it was coming up in one area when I started the game, so I deleted the game and dowloaded it again. This did the trick. Now I'm getting the error in a different location, and it won't go away even when I delete the game, clear the cache, and download again. Any ideas?
