I've been having a problem with my copy of Dead Island. It worked for a while, but suddenly started freezing after the opening cinematic. I've tried it with two different consoles and two different copies of the game, both brand new, and it freezes on both. However, it will only freeze when I'm signed into my Gamertag. If I go in on another profile or with none, it will work fine. I've even tried getting the game started with another profile, then signing into mine and as soon as mine's signed in the system freezes. I haven't encountered this problem with any other game but Dead Island, but it happens consistently on both copies. I've tried installing the game, clearing my system cache, deleting corrupt files (there were none), deleting updates from the console, unplugging everything, removing the hard drive, everything, but it still freezes everytime. A support person told me it's because my NAT type is Moderate, although it still freezes even when I'm offline. Does anyone have any idea what I can do to fix this?
