First let me say that I purchased the Halo 4 special edition xbox. This came with everything I needed. Now when I downloaded the Crimson Map pack the other day I was able to play it. Now whenever I get on Halo, it loads by saying "Unable to Validate Please make sure you are connected to Xbox LIVE and have the War Games Pass downloaded." I then click ok and am able to play matchmaking. However, I am not allowed to play the Crimson Maps. I checked in my system memory and it shows that I have crimson map pack downloaded as well as War Games Pass. Can someone please help me out?
