[Scary Bear D]

I Down loaded Mythic Map Pack, Cold Storage, and Heroic map pack. But when i try to play on ranked play list, my name blinks and it says One or more players do not have the maps required to play on this list. HELP!!!

Go to marketplace then go to your downloads and redownload them, it'll take no longer than 10 seconds each. It happens to me all the time, it's annoying I know because you want to start playing but it's just what you need to do.

First you must go to custom games clik on ur maps and it will say recieving data. You wait a minute then it will go away. Click on ur maps and check to make sure there there which they should be then you can go to matchmaking and play.
