Ok, I get through the prologue and as i drop through the glass roof and get the achievement and it goes to the loading screen it pops up. " Disc Error, Disc is unreadable." note this is a downloaded game and there is no disc involved with it period. I have done everything Xbox Support would have me do after being in contact with them for a hour or so. I am currently waiting on a response for their support team or something like that he said. I am just wondering if anyone may have any advice from me. I am redownloading the game, again. Cleared Cache, deleted and reinstalled profile. What else is there to do?
