Devil'sAdvocate wrotei got this on my modded xbox 360,on Lt+3.0 and i can only play the game when it is NOT installed,if its installed,it didnt go in to the game and gave me disc error or something and the xbox booted,quick search on google said that the people who burn CD's need to use something called ihas and something about truncating,im not too up about modding and stuff
disc unauthorized
I had the same issue, you must buy verbatim discs
