Delete your current version of java from the add/remove programs, then download the current version from here using the offline installer: http://www.java.com/en/download/manual.jsp

Then delete your LW Preferences folder(while LW is closed), points 2 & 3 in this thread: Fixes for Limewire when LW isn't operating as it should!
