For some stupid reason, Halo 3 doesn't allow me to play the older maps(epitaph,valhalla,isolation,last resort, etc.) with the exception that i can play high ground and construct but does not show a picture of the map. The game allows me to play ALL of the new maps but none of the old maps so please answer this question because it is bugging me oh and everytime i select an old map my xbox 360 makes this whining sound.
