OOps! I goofed. Wanted to make this correction:  I must have messed up copying some of the python files over from the Poser 7 folder to the Poser 8 one. I went back to my original bought zips. So far, I've installed Semidieu's Advanced Render Settings and RDNA Render Studio for Poser that he and Colm did. Both are working. I'm going to try more later.
