HaloMods "Classic" Read-only Archive

I have my mod, but when I fire guns with bullets, instead of showing up, as well, holes, it shows up as llittle black boxes. I thought it was due to my ammo meter change, but I turned it back and its still a black box. Any help?

And can I change a mod from Halo to a seperate map on Halo CE? I do have backups, but im asking; any method of doing this?
