Not All Radio Stations Are Visible

For some reason, after I deleted my Audirvana app download and then re-downloaded it, I can’t get all radio stations to load. If I go to radio stations by Language, or Country, or High Quality, I only see half of what should be available. I’m thinking that I may need to clean everything Audirvana Studio related, off my hard drive and install. Because the first version of the app worked flawlessly.
