Button mapping tools tree blank 2013PR

I just upgraded to soild works 2013 pre release. My space pilot will not hold the button configurations. I opened button mapping, all fields are blank and the tool tree on the left side is blank. 3dconnexion told me to uninstall their drivers and remove registry entries and do a clean install, which I did. but still a blank tool tree. Can anybody help?
