The Bad serial number problem...

[Hesselberg 0]

So i recently bought ArmA II: Combined Operations, since it was on sale due to the autumn sale, and since i have been wanting to play DayZ for some time now... But i have run in to a couple of problem.. I have looked around for fixes for a couple of hours, but none have worked, so i am turning to the forums for help now.

First of all, i dont have the option to launch ArmA 2 as Combined Operations, which i have heard is needed, and when i open the "DayZ Commander", it says that i don't have ArmA II: Combined Operations, and if i want to buy it.. I have Installed ArmA 2, Arma 2: Operation arrowhead, and the Arma 2: operation arrowhead beta..

Now i can open Arma 2 itself just fine, but when it comes to Operation Arrowhead it's a whole other story. I can see the game launching, but after a little while it stops and says "Bad serial number given in setup".. I have tried to run steam as admin, and verify both games game caches, and it didn't work. I have tried to do the whole open run -> regedit -> and so on, but that also didn't work..

hope somebody can help, since i am really eager to play DayZ with my friends.

Bud, I'm pretty sure he tried looking it up and couldn't find it. The same reason he came here for help.

Tried the first vid already, and it didn't work... currently re-installing ArmA 2, and then Operation Arrowhead
