"Network Firewall is not functioning properly!"

Note: I know little about how Comodo (and all) firewalls work.

I recently updated the firewall & defense + and when I restarted was given an error:
“The network firewall is not functioning properly!”

I ran the diagnostics but it didn’t find a problem, I know I am being vague, but I really don’t know what the problem is.

I am running Windows XP (64-bit) SP2, and spyware/anti-virus programs installed: spyware blaster, Spybot S&D, Ad-Aware, Avast! (incase one of these is interfering with comodo…).

I’m sorry about being rather clueless :frowning:
Thanks in advance!

Right, when I tried to install AVG’s firewall, it also gave me an error and said it couldn’t start because there was a problem communicating with a driver, could this be the problem with comodo (and how do I fix it)?
I am going to update all my drivers now, if someone could help (if updating drivers doesn’t work) that would be great.

Yay for the triple post, but I solved this problem by updating my graphics card drivers (nvidia), if anyone else has similar problems, I suggest updating drivers.
