Milkshape Guesst Plugin not showing up

[Darkholme]

I just got Milkshape 3d, and copied zero points and guessts exporter into the folder. when I open it, the exporter doesnt show in the export list, and there isnt one in import either.

I'd like to try my hand at using Milkshape to edit, but I need to get my Mdls and Mdxs in there first.

Any advice?
