Try downloading it from the product main page.
thanks for the help.. for others trying to correct this on mac you need to go to your app and right click > show package contents
then go to
contents / MacOS
drop the override.cfg in there. option 2 worked fine for me.
@radmatt you should add these things to the app settings if possible. you designed a great dialogue editor but it needs a bit of love. I've been trying quite a few of these apps and this is my favorite. hope you continue to polish and support the project.
