I installed the utility only upgrade on my P5 crashed completely. I ended up uninstalling and reinstalling just to get the original P4 to work. Upon executing the Poser 5 file, my screen went black and I got this Windows error: Error: 0E: 018F: BFF6C172 When I hit Ctrl,Alt,Del to restart, I got a second error: Error: OE: 0028: C002F972 Had to turn the PC off and try again. I'm running WindowsME (against my will). Has anyone else had this problem? I e-mailed the bugs section listed in the update info. Meanwhile, I'll dream about well-rendered fire fly hair.
