It definitely is a PPP problem (I was just kidding above), and the only way to solve it would be to fix PPP. Just to avoid disappointment - you can have both P4 and PPP on your machine, but you should not try to merge it into the same folder. If you install PPP, just make a backup copy of your entire P4 folder, and then copy it back afterwards. On Mac you can simply delete/copy complete Poser folders without affecting the system or the separate copies.
