I need a different file converter! (MDX/MDL)

[Disabler]

I'm using War3FileConverter and when I convert a model from MDX to MDL to MDX again it shows up as nothing with warcraft 3 but it shows up just fine with the wc3viewer...
So I either need someone to help me with this converter or give me a link to another one.

Edit: It used to work. I made a marine model that shows up fine in warcraft 3.

I also got trubbles with this program. It worked before on my computer but not anymore. A heard something like if you put all the files in wrong folders or unistall and install it many times it stops working.
