The board was closed in 2008 and since CAV and CF both are included under the banner of CIS, it was move at some point to Discontinued Products but I haven’t heard anything about the Firewall element being discontinued.
Have you tried removing Windows Sockets Interface from the HIPS protected objects as described in my post in January? Not sure if it’d be related to the update issue or not as that was just for allowing internet connection with contained apps but worth a try.
