Blue Knight model not importing properly

[Gharbad]

Hey guys, so every time that I go to import the blue knight, it imports perfectly. The problem starts when I go to edit Arthas' model. I select the imported model, but every time that I do, whenever I reopen the model file, it's changed to custom, and is an .mdl file. It's happened about 10 times now, and it's getting annoying. So is there anyway to fix this? I'd really like to use the unit, but it's starting to give me a headache. The map was a custom one i'm building.

Edit: I've already created a 'units' folder in my wc3 folder, and put him in it. Forgot to type that in the first time.

It always changes to .mdl. If it imports correctly then there's no problem, is there?

There wouldn't be, but whenever I try to add it to the game, it's a big green and black box. Then this error appears on the editor that reads: "Could not load file: war3mapImported\TassiusKordual.mdl".

1. Download
2. Extract the files anyhere you like
3. Import TassiusKordual.mdx and the portrait file. You don't need to chance any paths.
4. Save.
5. Assing the model to a unit in object editor.

I tried that, and it just didn't work. It was a green and black square. Well, i've got it working now, but whenever I enter the game, he's invisible. :/ I can move him around, but his models just not there.

Edit: Ah, nevermind. I finally got it to work.
