Is it normal for the game to freeze and a popup window with some sort of error message to appear during online games? I've only played a few times and have seen it in all but one game.
The worst one left me out of the game permanently at the start, but the other two let me continue after a few seconds.
The error says something about being kicked, but I can continue after the popup goes away. My internet connection is good enough for voip, so an online game shouldn't be a problem.
