[XSI] Ragdoll --> Playermodel

Could anyone please tell me how to rig a ragdoll up in XSI? I can rig a model that wasn’t ever a ragdoll, just a polymesh when imported. But when I import a SMD ragdoll and try and
rig it ( after un-ragdollizing it…kind of ) the rigging process never works. I’ve used multiple methods, such as the CT_Reference, and the Rig From Guide. None of them have worked. The only part it rigs to is the feet.

Could anyone throw out some obvious error I am making? A process chart would be nice though.
