Attach points for Arthas?

Now, it might help you if you download the NerzuelArthas file (in the DL section, or on the front page) if you're going to help me.

Right. Since I want to keep down the size of the map, I can't use the whole NerzuelArthas file, since it's something like 1 MB or so... ah, maybe "alittle" less, but it's way to big.
So, what I want to do is to import the helmet (casqueNERZUL.mdx & casqueNERZUL.blp) and attach it to the Arthas model, wielding frostmourne (thou it's not really Arthas; it's skinned)

But it doesn't work.
Special Effect - Create a special effect attached to the (head) of Arthas [Wielding Frostmourne] 0005 <gen> using war3mapImported\casqueNERZUL.mdx

That should work, but it doesn't. Nothing shows up on his head. Now, I've come to the conclusion that...
1) Maybe I can't just import the two helmet files to a map, but I don't think so, since they show up in the WE when I change a unit's Model File to casqueNERZUL.mdx (although the unit doesn't show up in the game)
2) I don't know the right attach point for Arthas. What is it?

Hrmmm... The model is most likely not agreeing with the skin(blp). Ill go download that model and see what the path of the skin should be. Be right back.

- Slayer -

This is the Blp for the helment.

Textures\casqueNERZUL.blp

If that doesnt work tell me.

Or the guy didn't add the attachment points. Lazy people :P.
