PTD must be registered for continued use. This is accomplished by purchasing a PTD license and entering the license key in the options dialog. If no license key or an invalid license key is entered, PTD enters an evaluation mode. This mode allows full use of PTD for a set period of time, after which PTD can no longer be used until a valid license key is entered.
