Sorry to hear your problem, I remember your renders fondly.

I too have no problems with Poser 8.  There were some problems fixed by services packs, but I was not using those methods at the time.

When I bought new computer with Vista installed, every graphic program I had stopped working for me. I demand to maker to "side-grade" me back to XP.  No problems since.  Maybe I am lucky, but there are so many possible combinations of hardware and software, that some systems will be stinkers not matter what.
