Comodo Firewall Blocking my Isp from working

I Downloaded Comodo Firewall, Now my ISp won’t connect when I click on It. What do I do to fix it?

Did you agree to use the Comodo Secure DNS?

Anyway, you can go here…

and follow the instructions to manually enable it.

If this doesn’t work, you can still visit the link above
but when you get to the last image, you can choose the options to…

“obtain IP address automatically”
“obtain DNS address automatically”

Hope this helps.

EDIT: I gave you the VISTA/Windows 7 link above…you can also choose the XP
instructions, located to the left.
