I got a copy of Splinter Cell Blacklist from Amazon but it does not work on my Xbox 360. I tried the disc on my friend's Xbox and it worked fine. My Xbox does not detect the discs at all, sometimes it detects the second disc but the first disc never works. I don't think my Xbox has any problems because it can run all other games without any problems. I have talked to Microsoft and Ubisoft and both of them told me to do some stupid stuff like restarting the Xbox and clearing the system cache but none of them worked. What do you think? Is there a way to make the game work on my Xbox?

Note: I can't return the game, I live in Afghanistan and Amazon is in USA, returning the game would cost me twice the price of a brand new game.
