    The serial number I enter is invalid... and yet it's the only one I have.

      What do I do when I've had Photoshop for years and when I purchased a new computer it asked for my serial number to validate my ownership. I put it in and it says it's invalid.

       

      But it's the serial number from the sleeve of the disc!

       

      Help.
