a couple of days ago,i installed a trial version of photoshop cs5 extended. just recently, i activated and registered my serial key successfully but when i open the application, it's still in trial version.
You need to be more specific and provide system info and all that. Beyond that - if it works without showing you the trial screen when the program launcehs, everything seems to be okay. This could be merely a configuration error. You could always re-install the application with the serial then. For everything else contact support. Nobody here can handle serial number issues.
