Turning the old RoC Beta D&D animation into a model?

I downloaded the Beta pack, with the Deathanddecay/target.mdx files and imported them into my map.

What I would like to be able to do is create that model/animation over top of a unit.

I setup a basic trigger such that when i type makeit, it creates a special effect based off the imported deathanddecay.mdx file, overtop of a selected unit.

Problem you ask? Nothing appears over the unit. I assumed the game couldn't load the model due to a missing (beta) texture, but I can't convert the mdx file into an mdl file to check if that is the case.

Any ideas?
