when typing in the 2 codes from the limited edition on the xbox it says 'code invalid please use another code' ad when typing them in on the xbox web site it says 'opps that shouldnt have happened, youve found a glitch in the system'

How am i suppost to get these to work as i paid the extra for these bit and i want them.
(And yes i am typing the codes in right, had 2 friends try typing them in on my xbox for me to and still nothing)

maybe you bought the game at another country and it isn't available at your countrys XBL marketplace?
if not so, try it again or call the XBL customer service

nope definatly a uk game, even bought from Game. just not sure whats going on, but its really annoying.

Ive had the same problem today with the codes from the special edition. Just now i entered the codes on xbox.com and they worked

Yes, thank you Xarran. they worked for me now.
thanks again.
