Help with Halo 3 Heroic Map Pack?

[bobby15]

I downloaded today on my xbox with my hard drive with me profile. Now it won't let me play it unless I'm online. how do I fix this?

In all honesty, you can't. The best thing to do is sign into live, start up Halo 3, and then you can disconnect from Live, and you should still be able to play Mythic.

I had the same problem. Try re-downloading the maps. If you do this and it STILL doesn't work, then you need to, somehow, re-establish the map when not on live. Try setting up live, playing on the map for a few seconds, then quit it. Get off live, go to recent maps, and it should be there. If not, scout around in the forge/ custom games lobby for it.

To permanently remove this problem, however, I actually had to download the game onto my hard drive. If you choose to do this, make sure you download from a clean, sanitary disk for maximum efficiency.

Hope it helped.
