Ok so I downloaded the game and when I try to launch it, nothing happens.
I'm running Windows 8 beta, but ArmA 2 witch runs on the same engine more or less, works whit no problems.
The thing I noticed is I have a CD-key and the Activation key. I was asked for CD-key during installation, however it did not ask for Activation?
P.S. I downloaded the game from BIStore.
