I have a question about the DLC car packs. I purchased all the Forza Motorsport 6 car packs. I tried to play the game a few days ago and all the cars from the car packs are locked and when I try to use them it says I have to buy them again. I can’t even access the 10 year anniversary pack that came with the game. Why is that? Can anyone help with this issue? Thank for your time.
