Well now it's not giving me problems about recognizing the file, but it's still not loading correctly.  Her leg just shifts slightly, returns to normal and nothing changes!

Another update:  I tried again from scratch, and it does work in the Materials Folder BEFORE I try editing any files, after I go edit the mc6 to a pz2 it doesn't work in either the pose foler or the material folder.  I hope I'm explaining that correctly... point being after I edit, it won't load at all from any folder.  :(
