I keep experiancing this problem from time to time,
I get disconnected from the server, when I log back in I get another one.
Then when i try to log in i get to the char select screen and then it just stops there, I try pressing the start button but it doesn't work.
So i have to log back out try to login but same thing happens.
To get in game i have to keep pressing Enter real quickly before it stops on the char select screen.
But even if i do i get disconnected after few seconds. That's really annoying.
I tried restarting my pc, closing all programs in the background that didn't help.
So I came to conclusion maybe it's a server side problem.
I don't know maybe there's 70-80 online people cap or something.
So please look into this
