Tone Gen Pro 2.0 Killed App

I have an iPOD 5s. This paid APP worked fine on this device until they pushed out update 2.0. When I attempt to update the App says this version is not compatible with my device. Now Ive got a constant prompt for waiting update, no way to download it and no way to make the update go away. Nice way to treat a long time paying customer.
