Attempting to re-install Creative Suite 3 Premium I have lost the 2.3 premium upgrade serial number. I have all the discs and serial numbers for CS2 plus CS3. All serial numbers are verified but will not continue with out the update serial number.
Find your serial # http://helpx.adobe.com/x-productkb/global/find-serial-number.html
Also, since the activation server for CS2 is no longer available, it MAY be possible that you will not be able to activate your CS3 upgrade version Error: "Activation Server Unavailable" | CS2, Acrobat 7, Audition 3
I think you need to contact Adobe about this one, since other users in an open forum are not going to be able to help with a serial number problem
