Need help with running Arma 2 on Steam

Recommended Posts

I downloaded the pack on Steam, "Arma ll: Combined Operations" I believe it's called..

It lets me run Arma 2, but I can't run Arma 2 Operation Arrowhead.. it gives me these errors when I try to run it.

Yes, I ran Arma 2 to the main menu, even started the campaign.

Try "validating the integrity of your game cache". In your library, right click on operation arrowhead and select properties; it's in there somewhere!

Trying that now, I'll give you results in a second.

Okay, it's validating as we speak. Thanks both of you, I'll report back in a few minutes since validation takes a sec.

Ran Steam as admin, still says bad serial number.

It says to run the game as Admin? How do you do that? I right click it and I see no admin option.

Put a shortcut on my desktop, still no option for admin.
