My Firewall is broken!

I have been using Comodo Firewall for about a year now. Since yesterday it has stopped showing traffic reports, whatever I do it doesn’t show up in the traffic window and the arrows doesn’t show in the systray icon. If I click block all traffic it doesn’t block anything.
Comodo says everything is up to date and working perfectly.
??? ??? ???

Btw I have a Vaio VGN FZ11M notebook running Windows Vista Home Premium.

Is The Issue Started Happening After Upgrading CIS ?

Nope, it started a few days later.
I reinstalled it now, seems to be working at the moment.
