Theoretically. Could you borrow a freinds AW and install the disk version, then launch it through the "games & apps" without the disc since you'd have the licenses for the game on your xbox and GT.

Cause the problem seems to be the servers.. So just get a hard copy to do the install, and the update is less than a GB so it should fix this..

Any and all input is welcome... I also know that this isn't the most feasible thing, however... If you have a friend who is willing to help you out and sacrifice his COD AW time I don't see why this wouldn't work,.
