Thanks all. The plug-in problem isn't good, and if Poser utilises only 32 bit in render area then I'll probably just upgrade Poser Pro. and stick with 32 bit for a while. 

I only migrated to DS from P7 because of slow render times. I just tried one using V4 with no props except hair, v4 mat and 3 default lights no shadows.  The render (setting on the second up from draft) took 4 mins and 20 seconds(!). Rendering in DS with same setup took 45 seconds (but the skin looks much better in Poser).  Adding clothes and other props blows out the render times heaps and it's really frustrating. I'm also not sure if I should wait for the new DS version or upgrade to PP.  I just purchased Fabi's latest figure Bettine..she's really beautiful but I didn't read the fine print that her make up won't work in DS. Some of Surreality's fantastic products work best in Poser too. Decisions, decisions. It's getting a bit hard to justify spending money with this economy the way it's heading. :-/
