It says that you are missing a class (file). I'm exactly sure if this is the problem, but if the actual viewer runs on Java through browser, check if there is an update for the Java applet or whether it's enabled.
did you contact their support team? if your browsers permit Java applet execution and your Java install is OK... (did you check the path) maybe there is a problem on your control panel?
