I copied this message because it is my same problem, except I don't know what MRJ 2.25 is ...

"I am also experiencing a java application error. When attempting to launch LimeWire Pro I receive a Fatal Application Error.
The text of the error message reads as follows: “Unable To Launch Java Application. Unable to locate the application’s “main” class. The class “.com.limegroup.gnutella.gui.Main’ must be public and hav a “public static void main (String [])’ method LAX”. I am running Mac OS 9.2.2 and have MRJ 2.25 installed. I would appreciate any suggestions."

Help? Chett
