Just wanted to play a smooth round of tf2, so I started the game, wanted to go as usual to the H|H servers, but then BAM there was no server list just a message "steam beta needs to run" and the console showed up this message: "TASTE" isn't a valid key.
any ideas? wunna play tf2!

Edit: Restarting Steam fixed the problem, but the message in the console is still standing there, but as long as I can play properly I don't care about it.
