I recently added new RRD-PRO dimmers to Radio Ra 2 system using Essentials v11 program and had to upgrade to Essentials 12.9. I'm trying to activate the system and can activate the new RRD-PRO devices but cannot activate the previously connected devices. I get the activate page for the device and am directed to press device to activate, but when I press device to activate, not activation beep occurs. Do I need to do something with the existing devices to allow activation on new upgrade?
