you replace it with the original .map file.

Get your Halo CD, use WinRar to un-compressed cab5, or 4 I'm not sure exactly but one of them. There you can find your original maps. (Without re-installing)

Thats why its a good idea to back up your map files before you apply mods.

with hhht you have to have backup maps on before you apply mod, then select file then do revert
