I got the following email from them.


GOODBYE, RIFFSTATION PRO
________________________________________


We are sad to announce that Riffstation Pro (Mac/PC) will no longer be available for download.

We are immensely proud of the success Riffstation has experienced and of the legion of dedicated guitar players it has seen develop along the way. We'd like to thank you for your support over the years.

We will be coming out with an exciting new product soon. In the meantime, if you are using an older version of Riffstation Pro, we strongly recommend that you update to the latest version now to future-proof your app. It's free to download until March 15, 2019.
