All Security Monitoring Disabled ( Resolved - Corrupted Registry )

On startup the firewall disabled itself and keeps popping up several dialogue boxes stating application monitor, agent, network etc are not working and reinstalling the firewall MAY fix the problem. A reboot does not work. What firewall is this? It’s a ‘mission impossible’ self destructing type. None of the functions can be turned on from the interface either. i am reluctant to reinsatal and go through all that training again. Any ideas??
