"Queri, .P2Z files are Poser Pro Pack compressed poses. These are regular Pose files they are compressed using a Zip utility integrated into PPP." Thank you, I thought I was going crazy-- they're in Quim's Victor package which I don't think mentions ProPack only. They are called Pz2's in the ReadMe. I'll see about starting a thread on them tomorrow. When I have a brain again. Your program had no problem with those files at all. Read them beautifully. The files that bombed were the ProPack version of Vickie's essentials MapPack from Daz-- the darn exe didn't let me choose which to install. I thought, like every other mappack, the MATs would be in a separate folder, but they weren't. I'm so darn new. I know PPP means Pro Pack but I forgot. And fishing around in that mass of MAT files, I got confused. However, your program picked up every other Pro Pack item but got terminal on these. Basically, I'm trying to fend off senility by plunging into 3D which has always scared me. Then my 60th birthday will not be so scary. [I'm only partly joking, it has been a really good mental workout]
