heyas; web, if the laces make poser crash, they might have pentagons in them. use anthony appleyard's depent utility on your meshes. if you render and the invisible pieces don't reappear, then they're not there. if they do render, they're abnormal. say, web... ::rereading:: you say the first time you made it, the only problem was the back faces missing?? man, you shoulda left it! because that's normal. as long as the back faces aren't facing out and making your parts backwards... you can try running your mesh through maz's twoface utility, or... you can do it quick and easy if you import the obj into poser twice -- once with normals inverted, and then export both and weld the vertices. having double-faced polys is nice, but from experience, melding things this way (either method) can cause your mesh to mess up, too.
