Each LiveGrade Pro license key can be activated on one computer at a time. If an error message appears when you try to activate your license on a new computer please check if the license has been properly deactivated from the original computer.
You can do this check by logging into your Pomfort Account. The license status needs to be shown as “Inactive” for you to activate the license on another computer. If this is not the case, please deactivate your license from the computer that it’s shown as activated on.
Find more information about the Pomfort Account here.
Please note: The documentation is currently in transition from LiveGrade Pro version 3 to version 4 and may not be up to date yet.
