Problem with Having Multiple Skins of One Model

i followed masterslowpoke's Having Multiple Skins of One Model tutorial but when i place the new unit in WE it shows up as black/green checked box and when i reload the map in WE it says "could not load file: units\nightelf\MountainGiant\Magmatitan.mdl" twice. i didn't import the mdl, i imported the mdx and blp.
also when i load the map in Frozen Throne the new unit shows up as an unselectable shadow. thats in game not test. any suggestions?

You need to put the skin in a folder in your Warcraft III directory, C:\...\Warcraft III\Units\Nightelf\MountainGiant\Magnatian.mdx
for it to be visible it world edit. You also need to put the skin in the same folder structure as you wrote the path in the mdx. Import it to those paths.

100% correct masterslowpoke, thanx :D
