There is no such a thing as PoserPro 08.  It does have a proper name such as PoserPro, PoserPro 2010 or PoserPro 2011.  Another issue, the Pro series does have gamma correction defaulted to 2.2 in the render setting which means that the lilght set you are trying to use has not been optimized to gamma correction settings.  The lights are too hot, meaning they are set at too high an intensity.  You will need to tweak these setting to a lower value to compensate.
