Med - I tried the bias thing on the main light, but it only gave me a different blotchy look.  I think it started at .8.  New render attached.  (I did add the skin shader.)

Result is attached.

Robyn - I'm not sure I have the vocabulary to describe the lights in detail.  I tend to work intuitively, find lights from sets I have, and then modify them a bit.  (Moving, changing color, etc.)  I'm not very technical with Poser, though I'm learning.

In this light set, which came from DM's moon cult,  there were orignally 4 lights, all infinite.

2 are now infinite with no shadows.

1 light, an overhead one, is infinte but has shadows (which I didn't know until you asked).

The main light was an infitite that I turned into a spot. It is set to cast shadows.  It's min bias is now set to .15, though that didn't seem to help -- just made things different.

I am using a mid-level automatic render setting currently, where you get some shadows, etc but not final render quality.

Is this enough info to help?
