The only things that show up in the .mdx are "NetherRaySkinRed.blp", "SMOOTHREFLECT.BLP", "COLDBREATH32.BLP", and "GLOWBALL02.BLP" and they have no prior paths. I tried importing the .mdx with just those files and got something to work. It doesn't really look too "red" but idk the green one doesn't look "green" either.

Remove the war3mapimported\ from all the files in the .rar, and change the filepath of whichever texture you want to use to NeterRaySkinRed.blp.
