Crimson Map Pack Help Please

Okay, so I have the the War Games Map pack pass from Halo 4 LE Pre-Order. But for some reason I do not have the maps on my game. Anybody know why?

Do yiu have infinity actual kit on your download list and hd?
Then goto halo4 ingame menu
Xbox live marketplace should have a star beside it
Click it and wait it will queue and ask to confirm download

ya habia descargado el pack de mapas y despues de actualizar el juego ya no me permite jugarlo.
