HaloMods "Classic" Read-only Archive

Im hoping this is the right place for this topic...
Okay, anyway, whenever I try to make a Halo server on Custom Edition or just Halo, it brings up the "Gathering Exeption Data", and then it crashes.
Does anybody know how to fix it?

what map do u wanna host? ure map is probably corrupted, or u modded a map, and did something wrong

Even when i dont mod a map it does that
I tried Danger Canyon and Ice Fields, both modded but the modding program didnt bring up a error message. I also tryed hosting Blood Gulch unmodded

I get that too sometimes (once or twice)
I dunno why it happens.

So it cant be fixed?
Wow... Microsoft could be a lil more... working...
