Since the new design, my Proclaim at our church keeps shutting down. Often when getting the songs put in on Sunday AM and doing some form of customization. It does not do this from other locations, like home when I work on it. The last 3 Sundays it shut down between 4 and 6 times while trying to get a setup, and one midweek it shut down in the middle of service. HELP - what is going on with it?
