Lost all my Bindings in Configuration OH2

I am learning OH2 I was trying to install Z-stick and was getting the error /dev/ttyACM0 not found

In the process of following the different suggested fixes found on this site, I tried to uninstall the Zwave bindings and Zway bindings the system locked up. I rebooted and now I do not have any bindings showing under the config binding of PaperUI. Not sure what to do other than uninstall and re install.
