Well I tryed logging on zombies and popular maps #2 and I get an error message about some confirmation or something like that I don't remember the message exactly but it says that it can be fixed by disconnecting or closing game. I did both and still get the message on those servers and I'm only able to play on deathmatch.
Is this problem because I'm playing non-steam or maybe is some error in my client? Let me know what I can do since War-Lords are the only good servers for non-steamers.
