The beta registration code has expired and the url to renew still only has the code that expired in May. Is the application still in beta mode?

Yes, it is still in beta.

If you look at the other "beta key expired" message topics, you'll see a technique for being able to start MakeMKV with the expired key, until Mike updates the key.
