--- Comment #21 from Paul The Tall paulthetall@gmail.com --- "It's also reproducible in windows with unknown reasons. The thread was started in 2012 and the last person to have the problem was from June 2014."
That kinda arguments are bull, because if this was a general problem EA would be overwhelmed with reactions of the problem and they would have fixed this problem straight away. In this case it was probably a firewall or virusscan or something causing it.
It might of course point to the direction of "security" which means perhaps something with winsock or advapi dll....
