    Upgrade from Flash CS4 Professional to CS5.5 Professional fails


      I am informed that the serial number is valid but that it cannot find a version of Flash to upgrade from, despite the fact that CS4 is installed. On the drop down menu of valid products only Flash 5 is available. Any idea what's going on?
