I can't play multiplayer for I cannot get passed the login screen. It says "An error has occurred, Please check your Network Connectivity." I have tried everything in the forums. Also, I used to see the sharing tab in the properties menu. It is no longer there. I have hamachi as well. I use it for my minecraft server that I play with some of my friends. I would prefer not to have to delete that. My router is a linksys by cisco: Model WRT120n. I am running off of cable internet and do not have a static IP. Please help me out here. I don't play crysis alot but I have random urges to play. Everytime I try to play I cant login. I can rarely log in.

у меня так же!!! иногда спокойно захожу в мультиплейер...а бывает так что зайти целый день невозможно...пишет "Найдена ошибка,проверьте сетевое соединение" ну или что-то вроде того...пожалуйста подскажите решение проблемы!!!

I have a same problem!!! sometimes I passed login screen successfully...sometimes I can't...I don't know why it going wrong...please help someone with this problem!!
