This just started happening to me this week:
When I try to join a server from the Launcher, it just brings me to the Menu. When I try to join a server from the Menu, nothing happens when I press the "Join" button.
When I make a Skirmish game, everything walks fine for about five minutes, and then I get kicked to the Menu.
Rebooted, reinstalled, refreshed IP, any other ideas?
Thank you!
