Copybot Catwa Head

I think Fantasy is trying to say that after getting rid of the Demo label in Blender, during the upload process the weight button can't be clicked.  I've seen all sorts of solutions in dealing with this, but none of the methods used can modify the mesh model.  In the older mesh with a clear skeleton this wasn't a problem (like the older catwa heads), but with the newer mesh (Lelutka and the catwa 4.5) that don't seem to have a visible skeleton after extraction to Blender, how is that done?  Thanks!
