As far as I can tell, many people met this problem as well. Unfortunately, so as I did. During whole weekend I was trying to login but it always ended with error 2002. Somehow after 3-4 of waiting I managed to play yesterday but only 1.5 hours since I had job to go. If you want to play you should try to login on not popular time (morning for example) or try to siege queue over and over again – not the best options but I don’t think there are better.
