I just tried it and it's working for me, although I have also had this happen on occasion here and there in the past, you click on play and nothing happens, it just sits there and the counter doesn't start, going back and trying again later it then works. I've always attributed it to either the server is perhaps busy at the time or maybe the web page just didn't open properly. That would be my only two guesses. If the problem persists it could also be how you have something set up in your browser. O.K., that would be my only three guesses.
