I downloaded TTK via the XBox 360 home screen. I already owned the game and expansion 1 and 2. It worked perfect for my profile, but will not allow my son access when he signs in on his own. If I sign into the XBox, then he signs in to Xbox as second player, then he signs into the game...everything works fine. I chatted with XBox support and even went in and "shared" licenses, but that did not resolve the issue. I don't feel this is any different from the previous expansions where we did not have any sharing issues on the same console. Am I missing something?
