From directions below i did all up until it asked me to rename files... how do i do so? I clicked on name a cursor never came up for me to try to rename????

From the "Macintosh HD" icon on the desktop, navigate down into System -> Library -> Frameworks -> JavaVM.framework -> Versions -> Current -> Resources -> MacOS. Whew!!
Then COPY the "JavaApplicationStub" file.
Next go to Macintosh HD -> Applications -> LimeWire, and <Ctrl>-click on the LimeWire icon. Select "Show Package Contents" from the menu that pops up. In the window that pops up, go into the Contents folder, then into the MacOS folder.
Now PASTE the "JavaApplicationStub" file in here.
Finally, RENAME the file "LimeWire" to something else (e.g. "OldLimeWire"), and RENAME "JavaApplicationStub" to "LimeWire".
