Lost Subsonic license key!

[grubenpony]

Hello,
maybe someone here can help me.
I have been using Subsonic for 15 years.
For some reason my Subsonic installation asked me for my licence key. Unfortunately, I no longer knew it and sending it via https://subsonic.org/backend/requestLicense.view doesn't work (anymore) either, as I no longer have access to the old mail address.
What I do have is the Paypal ‘confirmation code’.
I have already written to mail@subsonic.org about the whole problem - unfortunately without getting an answer.

I remember that the licence key was somewhere in the registry. Can anyone help me with this? Possibly better by message...
Thanks for the help,
Tim Legler
