Error "Your license for this server has expired" after importing valid license file

ISSUE

After importing a new license file for Nintex Workflow or Forms, the following message might still appear in the designer:

Option 1

Make sure that the SharePoint Timer Service is running. If it isn't start it. If it is, restart it. Perform an IISRESET.

Option 2

If an IISReset fails to resolve the issue, clear the SharePoint Cache. For more information, see SharePoint 2010 – Clearing the Configuration Cache.

 

An IISReset should be enough to resolve this, as it will trigger the property update, however if the configuration cache has not been cleared/refreshed in some time then working through the above may be necessary.

ADDITIONAL INFORMATION

The license data is stored in a cached Farm property and occasionally this will fail to update.
