This is what i get when i open up the game from my desktop, from the browser all i get is a white screen.
I use to play this game without any problems so i know its not my system specs and I have the latest version of java installed.
Ive tried going to the URL but Chrome keeps putting up a 404 screen indicating that it cannot find the URL. Someone please help.
