I just upgraded from the demo to the paid version of the Mezzmo app on my Nexus 4.
Now I can't stream to my Kindle that has the demo apk.
The Mezzmo app cannot be found on the Amazon store for the Kindle Fire, as we know.
But the apk cannot be moved to the Kindle using "app backup and restore" because it's "protected".

How can I get around this? I'm assuming that Conceivia wouldn't mind since it's not available on Amazon anyway.
