Every once in a while we update our model average calibration profile list with new headphone models. In order to obtain these new profiles you need to reactivate Reference plugin (not Reference 3 room measurement app or Reference 4 Measure).
Press on the SW logo on the upper left side of the plug-in, then press "Add new product license" and enter your existing Reference activation key + email address.
Once you do that, the headphone profiles will be downloaded automatically to your "Sonarworks Projects" folder, located in your user folder on Windows and in your Library folder on Mac.
Sometimes an antivirus software or a firewall can block our plug-in's access to the internet, thus blocking the automatic download.
It should be possible to fix this using offline activation.
If this fails, please submit a request here.
