I've contacted steam several times about my issues. No reply. Steam doesn't care. Once they've got your money your not their problem anymore.

I bought the Arma 2 complete edition two weeks ago from Steam to play DayZ and I haven't played it even once yet due to start-up errors! I have literally tried everything! Nothing works and when it does it just creates new errors. DayZ Commander doesn't work! I give it correct direct paths to the files and it cant find them. My security doesn't interfere with it. I need an expert about the game and its software. I downloaded Arma 2 first, finished boot camp and exited safely. Then downloaded OA, when starting up OA it gives me a code and tells me to enter it when the game ask for it. The Game Never Ask For It! I have redownloaded everything numerous times. I have verified the files in administrative mode. When attempting to start up DayZ I first get this error. Failed to load file "C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\pmc\addons\air_pmc.pbo" - decryption of headers failed. Also Failed to load file "C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\baf\addons\missions_2_baf.pbo" - decryption of headers failed. The game continues to start up then it says "wrong code given in setup" Once it did start up (with errors of course) and at the home screen it said this. No entry 'bin\config.bin/CfgVehicles/Soldier_Crew_PMC.scope'. Then I tried joing a server and it gave me this error. Files "C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\baf\addons\language_baf.pbo", "C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\baf\addons\missions_2_baf.pbo", "C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\baf\addons\missions_baf.pbo", "C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\baf\addons\shapur_baf.pbo", "C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\baf\addons\sounds_baf.pbo", "C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\baf\addons\tracked_d_baf.pbo", ... are not signed by a key accepted by this server. To play on this server, remove listed files or install additional accepted keys. So, I have no clue what to do and need serious help with fixing this game. Please Advise!

I think I am missing the executable file. Steam also suggest that my security software may be interfering with it.

Doesn't work. "Could not find path to Arma2 Operation Arrowhead (arma20OA.exe)" - DayZ Commander

I have Arma 2, Arma 2 OA, Arma 2 PMC, Arma 2 BAF, and Arma 2 DayZ Mod installed. Steam also gave me a "OA Beta" download but I haven't installed it.

Steam. This is also the second time I downloaded OA and atempted to play Day Z. I also have checked the intergrity of game cache and it says for Arma 2, Arma 2 OA, and Day Z, that "All files successfully validated." EXCEPT for OA, it says "1 file missing and will be reaquired." It says the same thing everytime I check the intergrity.

I bought the Arma 2 complete edition off steam and dowloaded all the content that came with it. Then I started up Arma 2 and played around for 5 minutes then saved and exited. Next I started up OA and steam gave me a code and told me I need to enter it when the game ask for it. I played around on the game for about 5 minutes. The game never asked for a code. I looked around and played different missions and multiplayer and it never asked for the code. I assumed it was unneeded and I saved and exited and then tryed playing Day Z. When I start up Day Z I get this error. Failed to load file "C:\Program Files (x86)\Steam\steamapps\common\ARMA 2 Operation Arrowhead\BAF\addons\air_d_baf.pbo" - decryption of headers failed. I click 'okay' and the game continues to start-up and then it closes and says " Bad serial number given in setup " Please Help!
