We have been using ZaraRadio at our community radio station with great success so far. Monday we started a Pledge week and went live for the first time. The mixer is stand alone (as far as I know). We have to stop the ZaraRadio playlist when talking and then play again. All of a sudden, Zara Radio just freezes up. And we have to open the program again. This happens at random times and it is getting quite embarrassing at the moment. Any idea why this could be happening? We are absolutely desperate for help.
