What beyond Keybreeze Pro license is needed?
It looks like you may have been logged out when you purchased a license for Keybreeze Pro, so it didn't get associated to your account. I just associated it, so you should see it now when you go to https://keybreeze.com/order/manage. Try going there to activate Keybreeze Pro on your machine. Then you should be able to log into Sync.
