Check the invoice which edition you bought, e.g. Starter, Basic or Professional Edition and also Cloud Edition or life time license.
- Compare that with the edition you installed. The edition name can be found in the title bar (see screenshot, red box)
- If you installed the wrong edition, uninstall Licence Protector and install again. During the installation select the edition you bought
- If you installed the correct edition, copy the serial number from the invoice. Also compare the version number. A Serial Number for version 3 will not be accepted for version 4.
- Download a different version.
