I disabled firewall, now I can't turn it back on... help

Tthe “Turn on” button does nothing on any of thw screens… network, application, component.
How do you get the firewall to respond?

Have you tried to reboot your computer?
If you have, is cmdagent.exe running?


What did you do to “disable” the firewall?

And as Ragwing asked, have you rebooted since?
