ProMods

hello, im hoping im posting this in the right place, it seems like the mods aren't working for me, for some reason my game keeps crashing when i try to run the profile, also i can't seem to see the def mod in the mod manage in game, i have downloaded the right def file but it just gives me it as a .rar file and the promod mods as .scs files, can anyone help me out to fix everything?

If it keeps crashing on loading and you can't see the def, then it's probably not working because you are missing the def file!
The def file should not be a RAR, it should be an .scs file too.
