cannot edit .mhx import mesh in Blender, toolbar disappears, "Sculpt" mode disappears

This is a followup to Dec. 26 post, I still cannot import MH .mhx into blender and edit the mesh. I also notice that after saving as .blend, this toolbar disappears
Before saving the .mhx as .blend, the Object/Edit/Sculpt /Vertex/Texture/Weight menu
is populated, after opening saved blend, only 3 appear:
I can export .blend as .fbx to Maya/mudbox, I’d rather try Blender. Any help? I"m using current Blender and Makehuman.
