Reply to Iphone app, and I have run into a problem. Already..

Hi,
May not be the right place to post, so apologies etc.

So the Traktor Twitter feed shared that the app is now live for iphones. Awesome.

I went straight in and bought the app. Great

I turn the app on, and am surprised by it's nice and clean interface, and the deck view slider option. Classy

However, my issue is this: HOW DO I LOAD A TRACK????

I can see my tracks. I can see the artwork of my tracks. I can se the A/B/Load button, but for some reason, which I cannot fathom, I cant actually play/load my music


Any ideas?

Iphone 4S, up to date iOS etc. Soun turned on. App restarted a few times.


Many thanks!
