HaloMods "Classic" Read-only Archive

I went into HMT and followed the directions made on how to make a ghost fly like a pelican. I went to vehicles and chose ghost and selected pelican option just like directions were stated and tried to use halo. so, I had to overwrite it with my backup when it wouldn't work.

I have been using HMT and have made changes that have worked for other people, but when I try to setup my own game, it won't let me use that map. Please help.
