My systems are: dual 733 MHz PIII 1 Gigabyte of Ram each Geforce 4 MX boards or better The scene is very simple...just a ball moving around some. Yes I did install off of the cd-rom but I do not see a rendercow update executable (in my Vur Pro folder on my main unit)...is it on the cd-rom...I will check. Love your computer names btw :) Fillingim
