Wrong CD Key when updating Arma 2

[exasmic 2]

So I reinstalled arma 2 and arma 2 OA, after I made a fresh install on my PC.. Whenever I go to dayz commander or manual patching of arma 2, I get a wrong CD key message because of this, I cannot join any games. I tried doing shit in the files, reinstalling, verifying integrity, regedit etc. :\ Nothing seems to work..
