So when I try to play moon I get a disc unreadable game error. Everything else on Black Ops works for me though.. Including all the other zombie DLC from that map pack and the other map packs.. I've tried cleaning my disc(which has no scratches or fingerprints as I bought it a week ago), clearing my cache, re downloading my account, installing the game to my hdd, and restarting my console. Now with this whole xbox live status issue I can't sign in to live which is also annoying, but it still won't let my play the DLC offline. The game always comes up with the error during the loading screen with the bottom spinning symbol staying in the same spot. (Like the trearch symbol stops in the same spot every time i try to load the map. This has only happened to my one other time, and that was the first content drop from Cod Elite on MW3. After a day it just suddenly let me play the maps. I noticed this issue when i finished downloading the map yesterday and thought it may be the same thing, but after a day the problem remains. Anyway I was just wondering if anyone else is having a similar issue or is it just me? and Also does anybody have any suggestions for a solution?

tl;dr I get a disc unreadable error on moon and moon only. Why?
