ListenToChurch.com Stalled

What does stalled mean? and how can I avoid it? I really appreciate all the work put into this new site, but I was hunting for our old aleph stream address, as that play button on the black page would always play. I very seldom, if every had that stream address let me down. With this new site there could very well be something I'm doing wrong, or could change so I wouldn't get -- stalled.
