Due the upgrade of my OS, I lost my program. I tried to load the original disk, but setup asked for a serial number and the only serial number I have is the 24 digit number which did not work. How can I Activate my copy of CS4?

I lost my Photoshop CS4 due to an upgrade of my OS. I used the original disk to load the program. I used my S/N (24) digit, but then setup asked for my serial number, which I don't have. How do I get my CS4 activated? Thank you.
