I didn't make it!
I bought 2 of the map packs a while ago on my account (EX1), and when it ran out, I was too cheap to renew it and used a free gold month and made (EX2). With (EX2), I bought the newest cod 5 map pack. Once I finally recovered (EX1), I can't use my maps from (EX2), even though I can see them on my memory in my harddrive. Any clue how to be able to use them?
