Firewall Blue Screened Vista

Booted up Vista,
Security Center said COMODO Firewall was turned off, so I went to check it and it was turned off, then when I tried to turn it on again via the tray menu (-> firewall security level → safe mode) Vista blue secreened and kept doing so until I uninstalled CFW (in safe mode).
