Update your Java. Use the JRE offline installer & remove any other Java versions from your computer before you install the new one.
Java SE Downloads

Close LW. Check in Task Manager to see whether it's completely closed. If a LW process is running, end the process.
Now delete LW's preferences folder, found here C:\Documents and Settings\your username\.limewire.
Start LW & see if it connects.

If it doesn't connect, go here & download this file called gnutella.net & save it to your computer.
zSHARE - gnutella.net

Close LW.
Go back to C:\Documents and Settings\your username\.limewire, now open the .limewire folder.
Inside that folder, you'll see a file named gnutella.net (or it might be named gnutella). Delete that file. Copy & paste the file you downloaded into the .limewire folder (so it replaces the file that you've just deleted).

Close all the windows that you have open, start LW & see whether it connects.

Anybody else reading this, it won't work if you're using a new or newish version of LW. Rigsby67 has a very old LW.
If you have a newer version of LW, read the advice here.
