That skin shader, for all intent & purposes, is outdated for PP2012/P9.  EZSkin provides a better node arrangement based on BB's latest skin shader using true SSS math.  I bet your principle problem is lighting and the lack of understanding how Gamma Correction, or linear workflow, is applied within the new Poser Pro series. 

What lighting conditions exists on your stage? 

BTW, rendering with Gamma correction = 1 is similar to rendering in P9.  This is a feature you should learn and understand.
