Playback Freezes and Audio is Lost

Hi all, I just downloaded DJ Pro and love it. However, around every forty five minutes of play or so, when the automix switches from one deck to the other, I get a spinning circle over the colored level viewer (the one that that moves with the song) on the deck it is switching to. All playback stops. When I try to load a new song, it usually fails. If it does load, it plays, but no audio is produced from either deck and I have to restart the program to get audio back.

Has anyone run into this or have any tips for how to solve? I’m going to be using it for a friend’s wedding reception in about a month and would rather not have the music stop every hour…
