HaloMods "Classic" Read-only Archive

i use hmt and i modded blood gulch like changing the projectile and zoom on the guns etc.
and i made backups for all my maps and whenever i run halo it brings up that screen that says halo and has halo in the background but then it shifts to a black screen then brings me back to my desktop and a message that sais Halo-Fatal Error

problem We have detected that one of the halo pc files is missing or corrupt. we recommend removing and reinstalling the game. (levels\ui\ui)

then i changed it back to my regular maps and then i can play
what should i do

you destroyed your ui. thats what it means

did you try reinstalling like it said to?

Solution:reinstall halo or try replacing all you map files with the originals.

yeah i just reinstalled it and now i learned to make better files
