Remove your Java & then uninstall using the Offline Java installer. Also delete your LW prefs folder if you have one. See instructions here Fixes for Limewire.

If that doesn't fix it. Go to Start menu -> Programs -> LW -> Uninstall.
Then download & run this version Download ‘Other’ version & simply unzip & use!
