I'm trying to configure Radr (https://radr.dj/beta/) so Traktor and Radr will automatically tweet what I'm playing, as I play it.

I am currently trying to use the settings here: http://traktortips.com/tweet-your-dj-set-using-radr/ (Port: 8000, press the broadcasting button in traktor, etc etc.) but Radr doesn't pick up anything I play when I press "Start".
