Where I bought the products: I purchased Arma 2 Operation Arrowhead off of Steam, and I purchased Arma 2 from Amazon on the disc. What patch I'm on: I tried downloading the latest patch from http://www.arma2.com/beta-patch.php but I don't understand what to do with the files. On Dayz commander it says I'm on Arma 2: 103718. Launch Method: I was able to access the game through Playwithsix launcher, but now it's stopped working. My issue: I was told to verify my steam games cache for Arma 2 Operation Arrowhead, as the new patch came out, and was given the error message of: 14 files failed to validate and will be reaquired. I ignore it and I try and log on to a day z server through playwithsix and I get the error message " Addon 'dayz_anim' requires addon 'CA Dubbing_Counterattack' " Which is different to the error message that I normally get from logging on. I pressed ok and went onto the black loading screen. No entry 'bin\config.binCFgVehicles/Citizen1.scope'. Now I get this error message, and when I press OK on this, I'm redirected back to the Arma 2 OA main menu where I have to exit the game, and unable to play. After getting this issue I've tried: I was told from someone looking at a forum, that I should replace the addons folder for my Arma 2 , with the Addons folder from my Arma 2 OA. I did this and nothing happened. I've redownloaded ARMA 2 from the disc , ARMA 2 OA, day z commander and playwithsix.
