So this is what happened, I registered my limited edition and that worked fine. Logged into the game was super excited because I was rank 5. Attempted to play a multiplayer game, got into a server, sat in there for 10 minutes waiting for it to start. The game obviously never started so I backed out and attempted a different server. So then I get this error, "Serial Code in use". So what am I suppose to do? just not play? Like I just spent 60 dollars on this game plus I had it pre-ordered. This really needs to get fixed. This is not something to be taken lightly, it claims that the code that I technically just spent SIXTY dollars on is in use. I really hope you guys are working diligently on this. I still have a lot of faith in this game and Crytek. Do us proud, but please keep us posted on these issues. Let me know if there have been any fixes for this. Thank you.
