Hotfix (e1.5.3) Not logged in problem

[ParzivaI]

My game was working fine and i could acess multiplayer and play , after this hotfix.. i keep getting "not logged in message every 5 seconds, i press login button to establish connection and it sends me to the multiplayer lobby, my friends can't invite me, and if i go to the server list there are no servers... My friends are playing the multiplayer right now and im stuck between a broken lobby and a not logged in message , and before you ask, Yes i have good internet connection and yes i have steam auto-updates enabled
Any way i could fix this issue?

Looks like your game isn't fully update it, look there and you will probably find a solution.
