This typically occurs when you've been using a temporary or trial license key that is expiring and install an updated valid temporary/trial or permanent key.

The Orca system only re-validates the license key every 3 hours. The message will eventually clear, or you can go to the Admin->System Settings page and simply clear the message from the settings and save. If there is an issue with the license key the message will be re-generated at the next license key check.

You can also restart the Orca Console service, which will force an immediate license key validation check. Use caution with this approach as any active jobs could be negatively impacted.
