MMD/PMX: Making Model Parts FROM SCRATCH! [part 4]

I exported something from Blender to .X, but when I open it in PMXe, no matter what I click, I don't see anything. I followed all these steps, but it isn't doing what I wanted it to. It does open in PMDe, but I can't use PMDe for it because the thing in question is a really big stage and using .PMD makes the entire thing all mangled up.
