The application isn't available anymore. There is no information about it on the official website. I have used the Search on the website of the developer and no results was displayed. In this case, to reset the utility to the default font, perform a re-installation. It should bring the application to the default values. The next time you start the application, make sure to note or create a shortcut of the interface to see exactly what is the default font so when it happens again to know what to modify.
