For people getting the Type 2 error, there should be a file in your LimeWire installation directory called "limewire.lax." If you open that file in a text editor, there should be a line that reads:

lax.nl.macos.apple.menu.quit=false

Try changing this to read:

lax.nl.macos.apple.menu.quit=true

and see if you still get the error.
