Hi bluesman
What could be happening is when you went to upgrade from the official site, you are now getting a conflict.
You say you downloaded Limeware from a third party site, they could have changed some of the code in the prog to their own uses
Uninstall that ver, then try it from the official site which is
www.Limewire.com and see what happens also goto
www.java.com in install manually the latest ver, install the java Before you install Limewire
