Please help me, I can't move in any of my games.

I have tried all browsers, opera, mozilla, safari but none of these work. I have tried refreshing the page many times but it still doesn't work.

When I left mouse click on any piece nothing happens and when I right mouse click it doesn't give any options to move only to refresh.

Ok, I finally moved. Its still frustrating though, this isn't the first time that this has happened to me. I'm assuming this site wasn't designed so that users would spend over an hour trying to click on a piece to move it, so any suggestions on why this happened?
