Go back to LW.org & download the "Offline" LW version. http://www.limewire.com/english/content/download.shtml

Also, try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.) That will get rid of the incomplete LW program in your prefs (perhaps an older version.)
