honestly hossam, i have a retail copy of the game i use & i play on a pure retail xbox 360 so i have no issues with the game or TU. i think the problem might be a region issue or the TU & game have different title ids...not sure though, i haven't dabbled in anything related to modded xbox 360s as i don't have one.
this "offer" is closed, i recently sold my 360 copy of the game as i purchased the X1 goty version and didn't see the need to keep the 360 version around as nobody had posted in this thread in essentially a year until you posted.
