"Invalid session" either means the launcher said "play offline," or you are using cracked. If cracked is the case, "frachlitz" may have only been whitelisted because someone else actually bought the game with that name. If you bought the game, make sure it says "play" in the launcher when you start the game.

P.S. I'm leaving for school, so I can't help you anymore until later.
