Invalid cd-key error

Hey there, today i logged into dayz to meet the error: Registraition failed: invalid cdkey. so i started searching on google and trying to find the answer on how to fix this error, but i havent found a way to fix it yet. Therefor im posting this post and hoping there is any ideas on how to fix it.
The key im using is 100% legit and bought from steam, its never been used hacks on this pc / CD-Key and i havent used any sorts of cd key changers etc so its not stolen.. i really have no idea on how i can fix this.. really hope some1 know how to fix this.

Here is the picture of the error i get in the corner.

I will help you in a sec, need to make homework >

okey, i have tried reinstalling arma II didnt work..

Bump, i really need help solving this

I have the same problem as him :L anyone found a solution?

Method 1
1. Run Steam as Administrator
2. Go to Library
3. Right click on your Arma II Operation Arrowhead
4. Click on Properties
5. Go to Local Files
6. Press Verify Integrity of Game Cache
7. Launch and see if it works

Method 2
1. Go to Computer
2. Go to Program Files x86
3. Go to Steam
4. Go to Steamapps
5. Go to Common
6. Go to Arma II OA
7. Go to BESetup
8. Click on the file inside and let it update/download

Method 3
1. Go back to your Arma II OA folder
2. Go to BattlEye folder
3. Go to this link (BattlEye website) http://www.battleye.com/download.html
4. Download BEClient.dll and BEServer.dll for Arma II: Operation Arrowhead Windows 32Bit (If you have 64 bit it does not matter it still works)
5. Go back to the BattlEye folder and replace the BEClient.dll file and BEServer.dll file that is in there or just add them in there if they do not exist.
6. Run Steam as Administrator
7. Run DayZ or Arma II: OA

Note: You can also do this for the regular Arma II as well to see if it works. Just download the Arma II version of BEClient.dll and BEServer.Dll, Method II is also the same. Just go to the Arma II folder in Steamapps/Common to do the same. Do these methods in order if they do not work. For example, do method 2 if method 1 does not work, etc.

If none of these methods work, then sadly you are going to have to reinstall. If reinstalling does not work, you may have had your key stolen or you may just be truly fucked without a solution. I can almost guarantee one of the methods should work.

P.S: I wouldn't mind a thanks if this worked.

I had the same error, but weirdly the next day it was gone =O

Someone may have been fiddling with your CD Key or you may have re-installed the game.

Sounds like it may be you are missing a file or maybe one of the files are corrupted or your video card drivers are outdated. Try reinstalling DayZCommander/Six Launcher or whichever program you use to launch DayZ. If not, then a reinstall of the full game may be needed, video card drivers being outdated is less likely the problem. Also CaptainsKeys why not post the help here? It may benefit others that have the same problem as well.
