After server selection the screen goes black and to close the game I have to do it from the control panel.

This only happens when the servers are saturated. My value pack is running and I highly doubt someone will refund me for the time I can't play because of this problem.

I tried to connect from different networks and the problem persists.

Any real solution?

Have you tried all the basic stuff like deleting temp files?

I recommend sending a ticket for issues of that nature
