Great after serial key is in use i have now Serial code is incorrect A valid serial code is required to play multiplayer.
pfft im sick and tired of this **** seems more bugged then worth the money.
i want my money back.
did you have the limited edition version? if yes mabey you filled in the wrong code?
a solution can be if you can start up crysis fill in your serial key must be 20 letters our numbers
when you done that click singleplayer then go back multiplayer and fill in again
make sure you use the serial game to activate the game and not your limited edition code.
if nothing works i suggest calling customer service
