Clearing the Flash Cache in any browser is to simple right click in the empty Game area as it's loading, and moving that slider for memory usage to 0, and being sure that the check box is not clicked, then pressing update or whatever that button is. Then load the Game again. You will have to 'allow' flash to save to your hard drive and you will be asked by the game if you want to do that too. And that first load is a doozie, might take minutes. I've played the game in many browsers, it works well in all. IE, FF, Chrome, Opera, Safari, Seamonkey, Cometbird, & Iron.
Using a different browser will fix the problem temporarily, since every browser has its own flash cache. But you will not be able to play in your prefered browser until you clear that ones flash.
