Weird Errors! Help!

[Statik (DayZ) 2695]

Hey guys, I've been getting a TON of weird errors lately, here they are:

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 get this whenever I try to launch DayZ. DayZ goes ahead anyways, but I don't know what this means.

I get this whenever I launch arma 2: OA through steam, and it auto-closes whenever I hit "OK"

Include file x\cba\addons\main\scrip_macros_common.hpp not found.

I'm also getting "missing '.ModelOptics'" or something similar to that, whenever I try to load in to an editor mission, I hear this can be from problems with DLC? I have BAF, but I also get these errors when using a friends Steam account (he just wants me to use it to get some pictures using PMC) and he has BAF and PMC.

Also, I've been playing DayZ since June 2012, but all of a sudden in the last week, Norton keeps popping up blocking BE. This is what it says in the file insight

File: c:\Users\Robert\AppData\Local\arma 2 oa\BattlEye\BEClient.dll

Blocked

Thanks for any help!

What have you done/changed recently?

The first set of errors sounds like an issue with your key and the DLC attached.

Do you have multiple steam acounts or something? if so then its very possible that your trying to launch the game on a key that isnt binded to said DLC.

If how ever that isnt the case and the problem persists go ahead and delete both "PMC" & "BAF" in your arma2oa directory and when you relaunch the game it should re install the DLC.

As far as the Norton is concerned, im pretty sure you can white list particular files so it dosent block them? Im not completely sure as i hate that Anti-Virus, if its stopping your BEClient from updating, id recommend turning norton off, updating in-game, and turning it back on, should fix the problem.

Try all of that lot and let me know if you still have issues Statik.

Thanks, I believe I can add an exception, I'll look into it in a bit when I can get on.

But I think that it might be trying to launch the DLC with a key that isn't binded. I uninstalled PMC, but I think I'll have to go into my computer and delete the PMC files (if they're there), because I'm still getting the error.

While I'm at it, I'll probably just uninstall BAF and reinstall it.

Thanks again,
