Just upgraded and i cannot get my Russound CAA66 to work. I have installed the Russound 5.0 driver and I have setup the AV family with the Russound CAA Model and the correct com port but the driver does not pick it up.
I have a CAV66 and its working for me with myServer. Is the value for the Network Address set to 1 (assuming that you only have 1 CAA66 device)? If that is configured, then Dave may need to see your log files to help troubleshoot.
