LIMEWIRE PRO 5.2.1.3
JAVA JRE VERSION 6 UPDATE 16

I have had an issue with Limewire for about a month. When I try to open Limewire I'm directed to get the newest Java download.

I GET AN ERROR MESSAGE WHEN UPDATING JAVA. I AM UNABLE TO LOAD OR UNINSTALL JAVA.
I currently have Java 6 Update 13

When I try go to Windows Installer to update I receive an error message that this is not the correct version for my system. I tried all the available options from Vista directly from the Windows page.

Any help would be appreciated.
