Rigify Disappearing Bones

I created a rigify Human and matched the bones with my model and everything looked fine. When I generated the rig it only has the Head, Neck, Shoulders, Chest and Stomach. Is there some important rule i am missing to why it decided too not generate the rest of the rig?
Thanks!

Do you get any error message at the top of the blender interface such as

In File / User Preferences / File, have you enabled ‘Auto Run Python Scripts’
