Started dayz and "wrong serial given at startup"

[Axxassin 49]

today while ging to enjoy another day of playing the dayz mod and i got this little surprise as i started up the game "wrong serial given at startup"

at first i was freaking out thinking that someone stole my cd-key or something but then i searched the internet for solutions

someone said that i need to start arma2 and arma2 OA at the same time to update the cdkeywhateverthishitmeans, I could start arma 2 bot not Arma 2 OA beacuse it is still giving me an error "wrong serial given at startup", so i reinstalled the game fresh without any mods or anything and tried to install everything again with the guide I used when i first installed dayz but still every time i tried something it says "wrong serial given at startup" at this point im already relly pissed and out of ideas so im asking for help here

if there is no way to fix this, i dont really care because i will get the standalone when it comes out, but I would really like to play dayz until it comes out

1.Navigate to C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead

2. Run the file "_runA2CO_beta" (It's just past the folder icons)

It should now load!
