My husband bought TTK this morning for us on out 360 while I was at work. I come home to play it and it wont register TTK on my profile, only his! I was looking forward to this not only all day, but since I first found out that they were going to make TTK! WTH bungie? Reseting the console doesn't work, re-downloading doesn't work, nothing works! IF I give in and buy a copy for my own profile, I KNOW I won't be refunded, however, if it is only one copy per account I wish you would say so so I can stop sitting here and debating weather or not i should purchase my own.
