Ghostman is correct. The shaders for Rex and Roxie are quite complex, you need to edit them in the advanced material room.

Remove all the nodes in the material room. Then re-link the changed texture to the diffuse channel. Run EZ-skin. You may have to set it up for Roxie, I don't have a definition for her yet.
