Have you been moving elements in your workspace? It looks like you have docked your faceroom modules along with the joint editor in your faceroom tab. First move would be to go to Menu>Edit>General Preferences>Launch behavior ... pick "launch to factory scene' then restart Poser. If that doesn't fix this, come back and we'll see what the next step is.
