Every time i try and join a match i get a message saying "Serial Number in use."....... Wait........WHAT!?

So do I. This is ****! Can someone please help?

Same exact issue. Hey Crytek, it'd be cool with we could, y'know, play the game that we paid for.

already topics on this guys, theres no fix ive been searching too... As of right now both the SP and MP are unplayable for me im pretty bummed :/

It's sad to say it, but really the majority of the people that are able to play it right now are the ones that pirated it. Shame.

I actually purchased a physical copy from gamestop and it is giving me the same problem

Same issue but with Retail ed

Yea same here on retail..funny i can join servers that are empty but none that are populated
also quick match connects also but never fine anything

Well you guys can thank all the guys who downloaded the leaked game for this and if any of you guys were ones who downloaded the leak then **** YOU. Cause look what you've caused.

Probably you're right, however this is a security issue Crytek and EA. I do not care about the version that was leaked, I care that I paid for something and I'm not getting as it should be.

So, after fighting around with the very confusing "redeem your cupon" part for my preorder, now i get this problem as well.
I hope it gets fixed quickly, I one of the reasons i pre-ordered the game, was so that I can have a little competitive advantage over my German friends with whom I play a lot.

soooo. could this please get fixed asap?
I would like to play ^^

agreed, I am getting the same thing.

Finally get it to take my LE Bundle code, get the unlocks, now getting the "serial Number in use" also. Steam version.

Anyone else having a problem with the melee. Whenever I die and resume the game I can't melee and have to restart the whole game.

Same exact problem here, come on we didn't pre-order crysis 2 for nothing you know. Get us a fix or this is the last game I buy from you !

Add me on the list for people who can't play due to their serial apparently being in use. Why is it that noone can seem to get a release day game to work these days? It's almost like these companies WANT us to ditch our PCs and play on consoles.

Mine doesn't say Serial in Use, it just wont let me enter it...
Retail version

Running a quick torrent search, there is a keygen for this game already. Mine was purchased through steam as well (yes, mine is legit). I did the "right" thing and waited for the game to be released and purchased it.

My key, for the moment, is working just fine.

However, having said that... The fact that there IS already a keygen for this game does not bode well. I suspect that the key algorithm will need to be updated and everyone given new keys before this is all said and done.

It seems that the "leaked" version of the game might not have had executable encryption enabled, nor debug threads disabled, thus allowing anyone with a little knowledge of how assembly works to simply observe the key algorithm at work and generate a working keygen.

*THIS* is why PC games cost just as much as console games. Because they have to go through a LOT more hurdles on an unsecured platform. This is the price we pay for our flexibility and freedom from proprietary hardware, software and licenses.

While I do feel for those of you whose keys don't work, I'd suggest you contact Steam and report the issue, as ultimately, THEY are the ones liable for the sale, not the publishers. The retailers are the ones that have to deal with bad sales.

And no, I'm not saying don't complain here. That'd be stupid... as you should be heard (I know I would be raising a stink if it were me). Just keep it polite, ya know? Karma has a way of sticking it to you if you're too over the top.

Cheers.

hi guys, just so you know, we are aware of this issue and we're investigating possible solutions.

same issue, i can play the story mode, and multiplayer with no one in it. but if i try to join in on a server with people i get that error really annoying

Guys its just Ea games Moh had the same issues

i think i found a fix..... when you log in when you start the game it says you need a key modify that and add your key it working for me so far

Add me to the list of this "serial in use".
Steam purchase, promo code worked fine.

I agree with:

Crysis should make all people who's emails are attached to their accounts, legitimately(like steam..), and send them new codes that require MORE numbers, and change it's algorithim. thn block all the IP's of the users who are playing ill-legitimately with other's codes.


Also I would NOT recommend changing your key around, that'd be breaking the EULA I'd assume.

I'm in the same boat as most folks, I purchased my copy at gamestop got it this morning and am able to join empty lobbies, but not any with people in them. Plus it says Serial Number Already In Use. Now that was really funny since I just installed the game today.

my decision to buy this game when price drops seems to be a good one then, from the looks of it, legit users at the moment is getting screwed while i will be playing this game with dx11 and no issues at all in a month or 2
