thanks lord of the rings,
I can't seem to even locate the
MacOSX: _ OSX -> Users -> Account Name -> Library -> Preferences -> LimeWire.

there is no sign of limewire in the preferences file in the library.
Can I just install the LW4 and trash the install of the LW5 I previously installed.
Nothing at all runs when I click on the LW5 version.
Am I missing something here?
I appreciate your help.
