My suggestions would be:
1. Go to Add/Remove programs control panel & remove Java.
2. Downld the "Offline" java installer here
Java 1.5 (take the JRE) & then install it.
3. Delete your LW preferences whilst LW is CLOSED; instructions here:
Point #2 & 3 in Fixes for Limewire (sample image included.)
4. Make sure your firewall is properly configured to allow LW or FW to work with full access, & also make sure your modem/router has UPnP enabled (else you'll need to manually forward a port); instructions for all of these here
