Ok so i got the Arma 2 collection after waiting ages for it, got it for £25 off of steam. immediately starting downloading the core arma 2 game, then i downloaded the operation arrowhead add-on, then the private military company one, then british armed forces, and then the operation arrowhead beta, and finally the dayz mod. During all of these, it kept bringing up something to sign up to, can't quiet remember what it was. i tried to run the mod from the beta patch. but when it was running, something came up Failed to load file "C:\Program Files(x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead\pmc\addons\air_pmc.pbo" - Decryption of headers failed. then it came up with "invalid key given during setup" then i tried to vertify game cache of arma 2 operation arrowhead since that is where problem was coming from it said one file was missing and that it was downloading it. i then tried opening Dayz and it came up with Addon 'dayz_anim' requires addon 'CA_CommunityConfigurationProject_E' any help? i really want to play this game :( when i tried to play it, it would be stuck on waiting for authentication from server, then go to a black screen with a name, duration 0, then a disconnect button
