If you have Java Runtime Environment (JRE) installed on your machine, then
clicking the above link should automatically run Java Web Start. In this case you will
see a box with the message "Java Loading" on your screen (as shown below).
A couple of seconds after you saw this message, the lobby page will eventually
appear on your screen (as shown below). To get in to lobby enter your user name
and password.
Note: If you cannot get to this window, then the problem might be with jnlp files.
