Skinning Problems

I am new to Torque and have been having problems with correct skinning of my models I make. I have the Torque book, but that has not helped with this problem. I make a model on Milkshape, create a skin for it, and it looks great. When I tried loading it on Showtool (since I have multiple skins for different areas) it put the textures in wrong places! THEN, when I loaded it in Torque, it loaded with one of the skins on part of it, all the rest was gray. Next, I tried making a simple model with one skin for all of it, and when I loaded it into Torque it didn't have the skin on it, it was just gray.
