You don't happen to have Metacreations Painter3D installed do you? I seem to recall someone having trouble with Poser somehow using the IO plugins from Painter3D. Another thing to try is check your Poser shortcut, make sure the "start in" option points to the correct Poser folder, particularly if you have more than one Poser installation on your HD. The 4.03 patch has been know to screw that up. Regards- Lemurtek
