    Serial number problems with CS4

    UpstartThunder

      My cs4 production premium serial number wont work. I have uninstalled all adobe softwear and used the clean up tool, reinstaled cs4 but the serial still wont work.

      Could it be that I have one licence of cs5 in use on one computer at work? My CS4 came with CS5. The serial number works fine to regester it on the adobe website so I know it is correct. Please help.
