First got I purchased the new Xbox for my son a year ago. Bought him Gold. Then purchased DLC's for Call of Duty Games. My two daughters wanted Gold so bought one more gold membership. Realized it was cheaper for Family plan, so went ahead and got that setup so all three of my kids and I have Gold memberships. But the DLC wont work for me, telling my I have to purchase again. But work for all the accounts before I set up my Family Gold. How can I use the DLC's on my account?
