Comodo deleted my internet connection

I tried to install the new comodo 5. and I rebooted into windows vista and my internet connection was gone. I went back and reinstalled CIS 4.1.149672 and everything works fine.
I just wanted to post this problem on the board.

Probably the Comodo Firewall Driver was not uninstalled.

Uninstall CIS and reboot. When there is not internet connection look up the properties of your NIC and see if Comodo Firewall is still installed. If so uninstall it from there and reboot again. See image.
