Importing MHX

My goal is to import .mhx files to blender. I downloaded the latest nightly builds from both makehuman and grahical. everyone says that the latest builds are in sync. The MHX import option is not showing up in blender. And when I attempt to import the .MHX file, blender crashes!

I followed the instructions as to copying and pasting the files to blender, but still no such luck.

Can someone PLEASE help me as in regards to where to where to go, and EXACTLY where do i paste the scripts in blender. Or for that matter, EXACTLY what night build should I download?

All i am asking for is a point A to point be reference as to how to import mhx files into blender.

Forgive me, I am an artist first. This is logic stuff isn’t my cup of tea.
