Can't Connect to Servers and Error Upon Closing

I had no issues in the beta waves but since release I have been unable to join a server, I get this message: http://ift.tt/2tSr2MX
Also, when I close the game I get this error: http://ift.tt/2sUUiWk
I have verified the game files with Steam, reinstalled the game multiple times, deleted the "my games" folder and made exceptions for the game in my antivirus and firewall. None of this has worked.
