Run Steam as administrator, go to libraries, then right click Arma II OA, then click on properties, then local files, and finally verify integrity of game cache. Afterwards launch Arma II OA as normal. This should revert your key back to normal.
Ok so I tried a injector to see what happens and now when i try to even open Arma 2 OA it tells I have CD-Key problem and its only a hunch but it was the injector.. should my CD-Key files be this type? umm can someone help me? I am stumped soooo bad right now and DaRK's key change doesnt even open with this error: ummm... Please help?

still received same the error
Go to the same place you have in your screen shot, right click the arma 2 OA folder in regedit do Right click then permissions then add then type Everyone and select Allow Special permissions, if that does work select allow Full Control. Have fun
