Can't log in, simple as that. I go to the log in screen, takes an hour to log in, then it just says "cannot connect to server bloop bleep." Nobody else is having this problem, it just started happening at this update. I can't log in no matter what I do! I restarted my computer, reinstalled the game, turned off my firewall, nothing! This has never happened prior, and just started with this update.
Are you using steam?
If so, there is a simple solution (assuming you double checked to see if steam was working). Create a non-steam account. When you can't log in with steam, switch users and log in with your non-steam account. Log out, then switch back to using your steam account. It will now log in properly. This works for me every time.
Of course, if steam is down there is nothing you can do.
