If you are missing the headphone calibration profiles please try re-activating the plug-in in your DAW (not the room measurement software) with your activation key.
Press on the SW logo on the upper left side of the plug-in, then press "Add new product license" and enter your existing key + email address.
Once you do that, the headphone profiles will be downloaded automatically to your "Sonarworks Projects" folder, located under Documents on Windows and in your user folder on Mac.
Sometimes an antivurs 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.
