If you have not recently upgraded CORTEX versions and have a current temporary (i.e., not expired) or permanent license, CORTEX may suddenly report the need for you to re-activate and after activation, you'll find your previously working license has failed.
The most likely cause is some change in hardware configuration.
Our licensing works by linking an Activation Key generated on our server to a Computer ID generated on your local machine.
The Computer ID is generated using information about your physical machine, including network adapters, Windows Computer Name and storage configuration. If some of these things should change, CORTEX will report a discrepancy between the Key and the ID.
If you are making permanent hardware changes to your CORTEX system and experience this issue, please contact firstname.lastname@example.org
