Having issues with editing imported MakeHuman model

Hi, I'm hoping someone can point me in the right direction on this, I've got my MakeHuman model into Blender with the rigging so I can fine tune details with modelling. The problem is I can't get it into proper edit mode, there are no face, vertice or edge mode options. I can get it to wireframe with Z but can't do anything with the topography at all, all Blender seems to want to let me work with is the bones.
Have I missed something when I imported it, or am I missing a step in Blender? I've spent hours trying to google for an answer to no avail, it's really frustrating.
Thanks in advance!
