Yeah, I wouldn't use my version of the ZoneConverter if I were you, there's a better way.
You want to be getting hold of Mitselplik's ZoneConverter and output the zone as a POVRay 3.5 Mesh2 format file, then use the PoVImport.ms MaxScript that I've included in my latest Model Viewer to get the zone into Max.
I don't have the link for Mitselpik's converter here at work, but I know where my model viewer's kept
