Hi Slick.
Sorry for the late reply
Try this first, the java JRE6.u1 is not working for some so Get jre-1.5.11
Now! Go to,
START/Set Program Access/Change or Remove Programs,
now completely remove all versions of java.
Re BOOT Your computer NOW.
Now! Use this Link to get (jre-1.5.11) Use the off line installer, NOT the (recommended) one,
Java SE Downloads - Previous Release - JDK 5
When Download is completed.
Disconnect from internet, close ALL apps n reinstall java.
NEXT, Turn XP Firewall off, 2 Firewalls running at the same time Conflict.
If that don't fix it,
Try to delete Firewall permissions in Norton, Limewire will re apply.
Let us know how you get on.
Your servant.
Peace.
