    Photoshop CS2 invalid user name or serial number


      Application won't open and I receive the following message:

      " Your photoshop user name, organization, or serial number is missing or invalid. The application cannot continue and must now exit"

      The application was downloaded from adobe to replace a legitimate copy of CS2 which would not operate on windows 7. This was some time ago and the application worked, but it doesn't now.

      What to do?
