I believe after latest windows updates the Hub stopped showing up in system tray or even open. It does shows in the task manager. I already tried uninstalling and reinstalling. I already tried deleting 3 keys from the registry. I already added in the firewall both CC3 and hub.
I won't do a fresh windows install.
