Map Pack Validation

I bought the war games map pack at a gamestop. entered it. it worked for a while, then i got into mortal kombat again, came back and now it is saying “unable to validate: please make sure you are connected to xbox live and have the war games map pack downloaded.” when i cleary have the crimson map pack already downloaded. can someone help

All you need to do is re download the map pack and the problem should be fixed.
Hopefully that fixes it for you!!!
