If you licensed or upgraded Hindenburg since the 25th November 2021, you no longer need a Licence Key.
All you do is "Sign in" to the app in the "Manage My Account" menu with the details used to create your account (email and password).
If you have an old Licence Key, you may have to "Change Licence" to access the Sign In option.
Be sure to download the latest version of Hindenburg, you will find a download button in your account when you log in.
