So, i bought Arma 2 and OA not long ago and since the beginning i have had problems, i cant go onto battleye servers it gives me that battleye initialized error, and if i try to use DayZ Commander it says i have the wrong CD key, also it can't find the Arma OA file and if i set it myself to the right file, it still dosent work. I can give some more errors but i think i'll be able to fix them.

No one can help me? Damn :/
