Hi, i got my XBOX360SLIM a few weeks ago, and got COD:MW3. After the update yesterday (23.2.12) I'm only getting the error "unable to read disc". Sometimes in mid-game, and sometimes at the loading of the game.. I've been searching this forum and the web for hours, and I've tried everything, when i un-installed the last update, i still got the error even playing offline. I've deleted the cache, I've cleaned the disc, deleted the cache, restarted my XBOX and now I don't know what to do.. PLEASE HELP ME!!
