HELLO i have talked to many many people about help for this problem and no one has managed to fix it so far so here it is.
the crimson map pack has stopped working while still installed i cannot use it in either multiplier or single player. i downloaded it through the war games map pass that i bought shortly after getting halo 4 but when i go into halo 4 i get a message saying “please make sure you are connected to xbox live and that the war games map pass is downloaded” i realy need to know how to fix this because i dont not want to have to rebuy the map pack
