[QUOTE=Crispy;305078]Are you running Steam and connected to the internet when you start the game?
You need to be in Online mode when you start the game, even if you intend to switch to offline mode later to play in Solo only.[/QUOTE]
Im getting a similar error except its crashing me straight to desktop without any errors, and im not launching steam in offline mode either
Start game can run fine perfectly for how ever long, leave a server close down the game play sometime later may or may not work properly, and then some times i will get get a random crash to desktop with no error or message(event viewer has nothing), and in-game when this happens to me other people can see a message that says “could not authenticate user neg” and then i can sometimes get back in perfectly other times it will do it again a few minutes later.
