Unable to install updates


I recently downloaded the CIS version 3.8.65951.477_XP_Vista_x32 from Cnet. I installed only the firewall.
Now when i try to look up the updates and then install them I am always getting the error
“Internet connection lost”
My system runs on XP_sp3
Any remedies?

I Would Recommend You To Download And Install The Latest Version Of CIS Version 3.9.95478.509 From This Link.
