Error with Vertex Modify

I'm trying to edit a very simple MDL model (a cliff doodad) with Oinkerwinkle's Vertex Modify program. However, when I try to open the model with it, the program says "Run-time error 9: Subscript out of range" and crashes. Any suggestions how I could get this working? I posted the .mdl file in Oinkerwinkle's MDL-editing forum.

I will appreciate any help a lot.

This should be in the MDL editing forum.

He posted this there, too. It's all dealt with.

Yes, it is. It works now. Thanks a lot, Oinkerwinkle. This was my first post here at wc3campaigns so I was a little confused where to put it. Found the right place a little too late.
