when i try and join a server/ any server a message pops up saying either "you have lost connection to this session" or just "you have lost connection" and sometimes "invalid parameter" and when this happens my internet connection cuts off (eg: i cant surf the web or anything) and i have to wait 1 to 2 mintues before it reconnects. I turned off my firewall but this still happens.......any ideas?

cheers.

Same here. i get kicked all the time!

hopefully some sort of fix/solution comes out soon :/

um not sure but I know I have a killer k1 card and I have to run crysis 2 in app mode or I get that. The ports to forward are TCP: 80, 64100, 6667, 29900, 2990, 2891
UDP: 27900, 27901, 64100. i did this on my router not sure if it helped but you can try it.

Nope, all of them open (PortChecker checked) and still Strict NAT.

Same problem. Hope there will be a fix for it soon

i have the same problem. my nat type is "moderate" though.

couldnt play 1 multiplayer game. im glad though that im not the only one who has that "internet connection goes completely down" problem.
