Hi Curtgruber
I had this same problem and I fixed by:-
[1] Uninstall the old version before installing the new -- delete the old LW folders from the Programs directory before installing the new version
[2] Ensure that you have java script J2SE Runtime Environment 5.0 (Jre ver 5) if not download from here:-
Archive: Download Java 2 Platform Standard Edition (J2SE) 5.0 Update 11 * Uninstall Limewire by using LW uninstall program not the add/remove control panel
start -> all Programs -> Limewire -> Uninstall
Hope this helps -- please let us know -- Thanx
