Beginning with LightLogger version 2.2.3, the notice is displayed only when the Admin Panel is opened. In earlier versions of LightLogger, the notice is displayed to anyone using your computer.
When your paid or trial license key expires, you must buy a new paid license key to continue using LightLogger. For instructions on buying a new paid license key, see How do I purchase a paid license key and activate it?
