Actually it is Amazon's fault as they are blocking the DishAnywhere app from their app store.
You can bypass Amazon by downloading the 1MobileMarket app, it includes a lot of apps that Amazon doesn't carry in their app store.
I downloaded this from 1MobileMarket app and the Dish Anywhere App would not work. It had an error message it needed to update to find a "library" and crashed.
I have the new Fire HDX so perhaps there is something specific with this model, I do not know.
I removed the app, tried again, and same result. I found it from another source and the same result.
