This has been happening to me whenever a server changes maps... when it does, first I get disconnected, or i press cancel and then I try to rejoin and it says "... CD KEY IN USE..."
So then i wait... and wait... and wait... =X and yes, stat checking is off
[18:14] <Panther> i got the same msg
[18:14] <Panther> on my original key too
[18:14] <Panther> so i udnno
[18:14] <Panther> but
[18:14] <Panther> after i got it
[18:14] <Panther> i hosted my own server
[18:14] <Panther> and people joined
[18:14] <Panther> so i could still play
[18:14] <Panther> you can try that
Perhaps the server is caching the key for TOOOO LONG???
