Sorry to post yet another message, but I'm trying to give as many clues as possible, in the hope that someone might be able to help me. I just TRIED to run the Pro-Pack memory patch (I've reinstalled P4 and the Pro-Pack). It won't work, because it says I don't have a valid Poser installation - even though it found the Poser directory etc when I ran it. Now I'm REALLY depressed. Morph
