PDF Creator activation failed on a LIFETIME license

Hello, I purchased a PDF Creator Lifetime license and now for some reason, I'm now getting the following error, see image attached.

When I click on the "blue" link of the License screen labeled "Manage licenses" and it takes me to "https://license.pdfforge.org/" and displays:

503 Service Unavailable

No server is available to handle this request.


sorry for the trouble.
Even though it is a lifetime license, the activation needs to get updated regularly (to make refunds possible and to prevent the usage on an unlimited amount of machines). Usually, this all happens in the background and you won’t need to perform an activation again.
Most likely there was a temporary connection problem with our license server, could you please try again and let us know if you are still getting this error?
Please also check that no firewall or proxy server is blocking the connection to license.pdfforge.org on your end.

Best regards,
