I think you urgently need to change the setting in Poser 6 that all morphs are saved to an external binary file. In the settings there. Then it will work. And save or save as - i don't think this makes a difference. But saving as pz3 is probably more important, not saving as (compressed) pzz. Dito with the geometry, i think it is important to use obj and not obz (compressed too). Tose compressions caused problems in the past and maybe still does in the trial version you have!
