Crimson Map Pack Downloading Problems

Hello, I downloaded the crimson map pack, but I cannot access the content. When I open Halo 4, a message pops up saying: “Please make sure you are connected to xbox live and have the war games map pass downloaded”. I keep trying to delete and re-download it, but it won’t work. If I needed a map pass downloaded to use the maps, why would they offer the crimson map pack as a separate purchase?

Have you tried this?

> I downloaded the Crimson Map Pack as part of the “14 Day – Buy and Play” program, then purchased the Crimson Map Pack offer. I’m getting an error when I try to launch Halo 4 saying “Unable to validate. Please make sure you are connected to Xbox LIVE and have the War Games Pass downloaded.” How can I fix this?
