Tom Clancy's Rainbow Six 3: Raven Shield - Key Server Not Responding?

[Sedmire]

I recently applied the latest 1.1 No-CD crack to Raven Shield, and now when I try to get onto a server online, it tells me that they Key Server is not responding. Is this a result of my using the crack, or is the key server really down? I don't expect anyone to really know if it's truly down or not, but I figured it might be a more generic message that is sent to me because I have installed the crack.
