I have Mac PPC and OS 8.1. I installed the lastest java runtime that
comes with it but limewire won't work. I even reinstalled it but I get this message:

UNABLE TO LAUNCH JAVA APPLICATION


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

What does this mean?
