I was playing for about 30 minutes.  I got kicked, (for lack of correct term).  The screen said K9arko dedication authentication fail.  I have never seen or heard of that.  I looked at the server it shows the IP, not the name, shows 24 players but --- for ping. Times out when I try to connect.  Any thoughts?  I'm a computer idiot so be gentle.

You've done nothing wrong. I think the server is down again. Looking at it now and the map is Unknown which means its not online. Happened last night too and it may take some time to fix.

World at War is still down.
