Wrong CD key

[mikkelrank 1]

Well i have this problem, every time i try to open up dayZ from steam or from DayZ commander it says ´Wrong CD key was given´

And it is only ArmA 2: OA that dosnt work. I can start up and play Arma 2.

And i have tryed these things and they didnt help me (I just bought the game again just to try to fix it but it didnt help at all)

- Reinstall game

- Start steam as Admin

- Regedit

- Restart pc

- Verify Integrity of game cache (Every time i do that i get this error: http://imgur.com/Dls5B9n )

- Make a new steam account and buy the game again

- Remove all the ArmA files from the Common folder.

- Cant delete this: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA

And i have note downloaded any software or anything like that and it was 3 days ago i just started not to work.

Please help my and Thanks:)

Close steam =)

Run as Administrator!

If you have CO, run arma 2, exit, then run OA.

Close steam then iopen normally.
