I'm a new user to limewire, and when I try to connect, I get this message:

Unable to launch Java Application
Unable to locate the application's 'main' class. the class 'com.limegroup.gnutella.gui.Main' must be public and have a 'public static void (String [])' method. (LAX)

Can anyone help to find out what this means? or what I need to download to get the system to work???
