Are your using a .97 version of a file? If you started the project in .95, it seems that some of the effects don't happen (at least for me). If that's the case I'd try to make a new project in the newer version. Otherwise, check your spelling, once I was trying to have a glossy attribute. I had named the attribute specular (make sure you didn't capitalize anything by the way, I done that too), set it to be a string, and typed glossy`. I don't know how I accidentally pressed the "`" key, but I did. The picture below shows reflection as a string inside the specular attribute (I set them up as separate attributes at first). So I hope this helps.
