OK. Live and Learn Dept: ProPack IS 4.03. The update numbered 4.2.166 is for non ProPack folks it seems because I re-installed Propack and It works fine. Here is an interesting note: When I had the patch installed it changed the opening screen to three different colored boxes, the ProPack changes this back to the three sepia colored boxes with the dancing figure. Ergo, I believe that the patch was trying to make Poser 4 forget it was Propacked! Anyway, I am back and working again. Thanks for the help.
