Nek, forget the log-in screen you are looking at. Just ignore that. It only shows that RuneAudio has started just fine. No need to log into the system here! Pull the plug from the monitor, start your computer and open a web browser.
If you are a Windows-user, "open the following address in your browser:
http://runeaudio or
http://runeaudio. (works if an Avahi/Bonjour client is installed) (OSX / Linux / Android) open the following address in your browser:
http://runeaudio.local"
