before the update i can login to multiplayer without any problems, after the update , every time i wanna login it's says "an error occurred please check network connection", can anybody help me =(

Its probably for the best, your not missing much.

A lot of people have been experiencing your problems. The only thing you can do is check your network, firewall settings etc., but its most likely a problem on crytek's side.

damn....ah well, all I Can Do is w8 until they fix this problem right
