The trial version has all of the features of the registered version, but you will be reminded that you are running the trial version with a "nag" screen each time you start the application. At the end of the trial period the application will no longer start, or will only operate in a limited functionality demo mode until you purchase a license or request a trial extension from Diablo Analytical.
