People often assume that Crytek/EA are one person who makes unanimous decisions on the forums, economics, development, patchwork on Crysis 2. That's definitely not the case. EA pushed Crysis 2's release date, and the game went gold unfinished. Crytek is working diligently to fix issues, while a whole separate group at EA's support center is responsible for managing these forums. The moderators' lack of news could be caused by a variety of issues - EA could be forcing them silent until a patch is complete, they could be lazy/bad at their job, etc.
Everyone's complaints have been heard, the message sent. Crytek is most likely working on it (they don't really have any other responsibilities).
Now, take a deep breath. Explore singleplayer if the multiplayer doesn't work. Chill out with some of your other games if Crysis 2 is having trouble launching. The problems exist, they are being worked on, and complaining is only wasting your time and nerves.
