Djay Pro 1.1.1 not working at all with OS X 9.5 Mavericks

I am using OS X 9.5 Mavericks with Numark Mixtrack controller. Downloaded Trial version of Djay Pro 1.1.1. Program opens, decks load but do not play! At all. Cannot do anything with the decks (Decks don’t respond to the mouse either). The decks appear to be locked. Suggestions?

djay Pro 1.1.1 should be working fine with Mac OS X 10.9.
Did you press the Play button after manually dragging a track on one of the decks?
Does the EQ / Crossfader respond?

Hi Adrien. Thanks for responding.

No, I haven’t tried manually dragging the tracks onto the decks. I used the load button on the Mixtrack. Afterward, I’ve pressed play using both the mouse and the Mixtrack: nothing happens (the play icon turns green, but that’s it).

Also, I cannot navigate to a point in or affect the loaded tracks (or video) in any way with the mouse.

In every other way, the software appears to be working (it analyzes bpm normally), but as I wrote previously, the decks appear to be locked somehow.
