I read though quite a few of the common threads on this forum, and have concluded that this is an EPIC Fail on someone's part to get the MP right, as far as the LE DLC stuff. OLD account from MP DEMO will screw you out of the LE DLC. I believe as I have read elsewhere that if you tie the LE DLC to the old account you are kind of **** out of luck as the servers don't remember the logins now, I have created a new account and MP works just fine (run as admin) I just don't get the LE DLC content that I have paid for. Ultimately they will have to unlock LE DLC for everyone in order to correct the situation (EPIC FAIL). I hope that get this sorted out sooner than later.

Please don't run around proclaiming:

OLD account from MP DEMO will screw you out of the LE DLC.

that is not true. The LE DLC works perfectly fine for me... Guess what? I'm using my demo account!
The LE DLC page has errors in it and may prevent the activation, that will be fixed.
If you can't login to your account in game it is probably because you are not typing your info correctly.

Besides, all the LE DLC is is some weapon skin that doesn't matter and will be outgrown in the later stages of the game, a pretty lame hologram feature that wastes 5 AR shots from an enemy or team mate who can't tell the difference, a dog tag that doesn't really look cool and I do not even care for and some xp that just puts you to level 5 so you can hit max level 3 minutes sooner than everyone else!

Who the **** do you think you are telling me not to proclaim something. **** the hell right off asshole. This is how I see it right now and it is a confirmed problem from EA.com live chat itself has told me so, it should be fixed but no ETA.

also i would like to add that the dlc was provided free with the game if you pre-ordered you didnt pay anything for it also just calm down its the first day just give things time to settle there no need to get worked up over this.

Listen there is reason to get worked up...people are told something and expect to get what they paid for...so don't say **** like you didnt pay for it or the limited edition stuff is not worth it...are you working for EA or something?...because I am not playing Crysis multiplayer until I start at level 5...so somebody better fix this...it is an Epic Fail and Crytek and EA should all be ashamed!!!!!

Nicely put, by the last fellow.
