After win8 update can't access firewall program rules

Just reset my PC. Win 8 updated. When it rebooted I was able to connect to the internet using IE but not firefox.

I remembered an issue in the past with Norton firewall settings causing an issue with firefox so I tried to access the program rules.

I clicked on settings then firewall and then on "program rules" and it just gets stuck at that point. It never continues. I had to re-boot.

After re-boot, same problem. Just stuck.

THANKS in advance
