Upgrade? Update? Huh? – GedView Review

I've had this app for years. After updating it today, I can't open a file saved earlier without responding to a popup message which refers to needing an "upgrade" also referred to as an "update." Both terms are used. Neither is defined or explained, and it isn't clear whether they're just referring to updating a file, or charging for an "upgrade" to the app, so I deleted the app. It never was that good anyway.
