You've got to re-link the bitmaps to the textures they use. I'm going to assume you have knowledge of the material editor and how to get around it, so here's what you do: Open up your material editor and go to the material/map browser menu (the button will say Standard by default, I don't know what the menu is technically called) and at the bottom of all the material types are the materials currently used in the scene. Select the iiko material and go to the diffuse maps they use. Select the image the map links to and find the uv_1 and uv_2 maps, wherever you saved the iikoRig folder to. I think there are two materials you have to do this with.
If this isn't clear I'll try to explain it better.
