When I upgraded Poser 4 with ProPack I found that stripped morph targets wouldn't load (no problems with regular ones). I believe I ended up loading the stripped .obj files to the figure in Poser 4, then moving the figure into ProPack's Runtime. (Are you sure the morph targets are for the figure you're trying to add them to?) And you can move morphs between characters with MartinC's nifty Maconstructor utility. HTH - Elisa/gryffnn
