Welcome to the community George!
The invalid serial number error is typically caused from a license that has been upgraded per a subscription contract that has since expired. As such, would you please either send me a Private Message (click on my philip.s profile name and then "Send this user a private message") with the serial number or contact our License Assistance Team for direct support.
