Hope someone can help. I just bought Forza 3 Ultimate Edition which included the Stig's garage car pack. This is a brand new copy. I opened the code card and there are three codes that I can redeem. I have tried redeeming all three codes and my xbox tells me that they are invalid. I have verified that I had inputted all the codes correctly. If someone can help me that would be great, or if not, how do I turn in a trouble ticket with MS?
