Can not connect to remote computer (Shows connecting status then returns to green Ready to connect s

I am am using v13

From connect screen I enter the Partner ID which I know is correct, remore control button is selcted and I select connect.  Status light goes from Green (Ready to Connect) to Orange (Connecting) but after a while just goes back to Green (Ready to Connect) .  I have tried uninstalling and reinstalling but it still does not work.  Yesterday it was working fine.
