I was playing on collection 4 and it kicked me out the game and now I have no DLC map packs and it is telling me to pay for them again when I bought them all already
Did you use the same Gamertag ?
HOW did you get them before ? Was it in the game menu from the ingame store ?
I have to work in the morning so if you dont get an answer PM me and I will replay later tommorow.
In the meantime you can look in your Xbox Live download history and find everything you downloaded before. Of course make sure it still says FREE.
Also one of the help people on the forum CutPurse can help you quite possibly. Send Him a PM with you gamertag as well with a good amount of details.
