Have you installed the Poser 4 upgrade to 4.03 and then the ProPack service pack 3? I'm just about to reinstall Poser 5 on my laptop, so I have all the updates assembled. This is what I install. Poser 4 Poser 4 memupdate Poser 403 updater.exe Pro Pack ProPackMemory update ProPack Service Release 3 Then I do 5 and it's service release. I dont know if the Pro Pack comes updated, mine didn't and I bought it wihtin the last 6 months. Emily
