Application Manager Asks for Pro X license but I only have Pro Installed

I recently bought a used computer and used a Time Machine Backup to replicate my last system. All my other Adobe CS 3 applications work, but when I try to launch Acrobat Professional, the Application Manager asks for a license to Pro X. There is no Pro X application on the machine.  My Pro license, obviously, doesn't work. How can I get the Application Manager to recognize the right Acrobat application?
