Application dies and doesn't restart

Randomly all of the Comodo firewall monitoring applications will stop working and I get a popup message saying that reinstalling the application may fix the problem. If I reboot it usually will start fine and then quit working again at some point.

Also, I am unable to turn on the monitoring options manually and even if I move the slider bar to block all traffic I still have an active, usable internet connection.

I have reinstalled the application and it is licensed. I’m running MCE 2005/ SP2.

Any suggestions?

Thanks
Thomas
