Invalid CD Key or Key In Use Message

[Valdarez]

I ocassionally receive a 'Invalid CD Key or Key In Use Message' when playing A&A on gamespy. It seems to be random in nature. Any idea what is causing this?

Ok, this is weird, one of the rooms that I was in earlier today, over 4 to 6 hours ago, still shows me as being in it. Come to think of it, it was after being in this room that the invalid CD key started.

I joined the room, became an observer, and downloaded a map, and then left. But, I'm apparently still there. :)
