I assume you have Mac OSX Some details of your system and set up will help. give us the details you see at Apple Icon>about this mac and what java you have installed This will be seen in Limewire about if you can open it, or Applicatios>utilities.

There is no uninstall programme. Drag the Limewire application to the trash. And do the same with the preferences folder which is at Users [your name or account on the comp]>library>preferences

EDIT also ...which Limewire version?
