Dev model has no geometries error?

[FWhyKay]

I'm not sure what I'm doing wrong. When i try to export my rigged mesh using GIMS IV, I'm getting the following error:

 

 

How do I prevent this error? Bit new to rigging for IV, it's pretty different from San Andreas from my experience so far.

 

I found a topic about something similar here: http://gtaforums.com/topic/845986-gims-iv-export-the-geometries-error-rig-not-works-after-attach-new-mesh-parts/

 

But I already have all the files that he says to extract, extracted into a folder (ignore the Outlook Item thing, I have Outlook installed so it thinks thats an Outlook file for it):

 

 

Quite confused here...help?
