Your individual calibration profile will be linked to your activation key.
Once the calibration process is complete, you will be notified and prompted to re-activate your headphone plug-in to get the profile.
To re-activate your plug-in press on the SW logo on the upper left side of the plug-in, then press "Add new product license" and enter your existing activation key and email address.
Once you do that, your individual headphone profile will be downloaded automatically to your "Sonarworks Projects" folder, located under Documents on Windows and in your user folder on Mac.
Make sure you are connected to the internet and no firewalls are keeping the plugin from accessing the web.
