yes i have. 

I clicked on it in the modeling area after i welded the feet and head to the torso.

normally i have two option.. i choose custom.. planar etc etc...  for some reason when i click on uv model a texture name apears next to an arrow like in the scene manager where the instances appear.  when i click on the name the arrow collapses and there is nothing else in the tree..

the uv modeller doesnt open up...
