I've tried everything everyone has suggested on these and other forums and still no luck with downloading the maps (installation failed message) - checked credit card (valid), wiped cache and halo 2 folder and redownloaded everything. Tried MS support via email (no response) and via phone (sorry busy will call you back, er still waiting). I would appreciate it if someone just said, sorry some 360s can't receive the new maps, here have your money back! How hard can it be for someone just to acknowledge the problems? Any other suggestions?
