HaloMods "Classic" Read-only Archive

And I can't figure out why! I've tried reinstalling several times (yes, legit copy) but every time I try to load The Maw level, the game freezes, or the one time it did load, I was dropped into this beige nothingness, but I could see my no-weapons reticle. I could also look around, but not move in any direction. Does anyone know where I could get a working maw level? or the filename (###.map)?

This is the first time It's ever happened...and of course, the first time I've gone through it with a legit copy...ironic eh?

did u do anything to it (like mods, etc...)? or possibly it might be a disk scratch
