Errors I'm Getting Trying to run OA

[ZedsDeadBaby 2287]

I did a fresh re-install of ARMA 2 and OA through Steam.

I've run ARMA 2 proper first. It runs fine and loads properly.

But when I attempt to run Operation Arrowhead I get the following errors. The first appears before the game launches, and the second when it drops back to desktop after the initial loading screen (before I get to the main menu).

I've "verified the integrity of the game cache" through Steam.

It doesn't seem to help.

Any advice would be greatly appreciated.

Delete your bin folder and have Steam recheck/redownload the missing files again? Looks to me like one of the files is corrupt, I'm no rocket surgeon but I'd check your hard drive for errors and defrag it as well just to be safe.

I actually had that same issue, too. Though I'm not too certain about exactly what caused it or how I fixed it...

Hmm... Did you install Day Z before running OA?

What seemed to fix is for me was a clean reinstall of OA, followed by actually running OA for a bit before installing Day Z.
