ok... THANK YOU ALL FOR YOUR SUGGESTIONS! So it has been narrowed down to Poser 8. I found my Poser 8 .exe files and installed them. Problem. I installed it but when I tried to use it required that I register it. When I tried an Error message said the past serial number waS INCORRECT AS WELL as the current serial number. And the past serial number space was blanked out. So...since I paid for this software, Renderosity has told me they only bought  Poser 11 and Forward. So, I'm looking for a workaround to have access to my Poser 8. Anyway to make it "stand alone"? Or any other suggestion? THANKS IN ADVANCE!
