Now Playing 2 app for streaming track listing

I’ve recently started using DJay Pro again after flirting with Engine DJ and I’m extremely happy with it. The update from version 4 to 5 has been excellent.

My question is regarding the ‘Now Playing 2’ app (it streams your current track listing) which I used with the previous version of DJay but I can’t seem to get to work with the new version. Is there something that has changed in the new version of DJay for this not to work, or should I be looking for problems at my end? The app was a bit flaky before the change anyway.
