Looking at your settings, is your diffuse_2 thats connected to the alternate diffuse an image map, or just a color? You may need to connect the texture to it (if it isn't a map already), as I believe alternate diffuse overrides the diffuse. Also, she sent out an e-mail with links for getting updated p5/p6 materials, so if you didn't get it, may want to ask about that also :)

Consider me insane if you wish, but is your reality any better?
