    A valid serial number not recognized

    Angelo Mascaro

      I installed my MasterCollection CS4 on a second PC and I got the message "The serial number you entered is not valid", but i'ts valid.

       

      I know there is no longer technical support on CS4, anyway since I paid for a LICENSE this license must work and if the authorization is done online, this service should be granted anyway.

       

      How can I make my license work?
