I am a newbie & also purchased V3 & M3 with the head & body morphs.  I have Poser Artist, which I guess is really Poser 4, and I believe I have properly installed the service release 3.  DAZ/3D says they (V3 & M3 morphs) are compatible with Poser 4.03.

I cannot get any of the morphs to work.  When I try to INJ one, I get an error that says "can't open xxx.pz2"  When I try to import the morph, .pz2 is not listed as a possible file type.  I've also purchased some other misc stuff that I also can't use because they're .pz2 files.

HELP!
