Cannot connect to update server

Since about Issue 22, one of our computers hasn't been able to connect to the server. I suspect there's a firewall issue, since several other programs haven't been able to connect to the internet. Is there any way to find out if a firewall has been installed on a computer? I can't find one, but it's possible one is running in the background and I just can't find it.

I'm assuming you're running windows and therefore have to say Yes, but normally it doesn't block CoX. we'd need more info though so checkout the sticky on posting tech help.
