PhotoKit Sharpener was correctly installed and working, but now it comes up with a demo dialog, what happened?
The odds are, your system clock is incorrectly set. To prevent the demo from working beyond the demo period, PhotoKit Sharpener’s security files places a time/date stamp within the file. Setting the clock in your system backwards or a long time in the future will cause PhotoKit Sharpener to be in demo mode. Normally, merely setting your clock to the correct time and date will fix this. However, there are situations where the PhotoKit Sharpener security file may become corrupt. In this case, you may need to reregister or reenter your serial number. If a simple re-register does not solve the problem, please e-mail Tech Support for additional info.
