i was playing MW3, and i accidently bumped my console while it was reading the disc. i realized the disc had gotten scrathed, but it didnt seem to bad. ( i had the same problem with COD black ops, but it still atleast let me load it) whenever i started launching MW3, it started loading just fine. after a couple of moments of the game loading, it says, "cannot read disc." i cleaned the disc several times and tried loading it, but the same air message kept appearing. i started exploring for help on the xbox support page, and i find that i can install it to my hard drive and play it. when i tried it, it only got about %13 installed until another air message appeared, telling me that it cannot install because the disc is scrathed. HELP!
