Model Invisible, why?

So I've put together this little model, it's Gul'dan with abit of glow, a dissipate animation and the Blood Mage attatchment points (Sphere).
However when tried in the WE it is invisible without animations, like how it get's when you import a model and forget the skins, but I haven't done anything with the skins. Anybody know what the problem is?

Bump.

Perhaps it's because you're using an .mdl instead of an .mdx?

There is absolutely no need to bump in this forum.

Consider that we don't actually know the answer.

No bumping, got it. Sorry.
Also, I imported it as .mdx, so that isn't the problem.

Just looked through the model, tested, tried a lot of things....

I just don't know why... sorry

Perhaps you need to import it as mdx and not mdl.

Already tried, doesn't work.

Solved!

As a guy over at Hive noticed, the dot after 4 (Summoner4.0) confused the WE, making the filename 0.mdx, a format not supported by the warcraft engine. Also it had an Event Object that didn't track anything.

Thanks everybody!
