Troubles adding source

I upgraded from kodi 17 beta to 17.1 I followed the instructions for a clean install and now when I try adding a source the OK does not light up for me to continue.
I tried on a second PC and having the same issue.

I turn of my firewall I even tried uninstalling my antivirus, nothing works past installing Kodi 17.1
I am running windows 10 with the latest updates, does anyone know why this is happening ?
