Thanks for the update, I guess now I can stop pulling my hair out

"Combined Operations" is actually two separate games. Firstly you need to download and install ArmA 2, then download and install OA to the same directory as ArmA 2, then run the 1.60 patch which should patch first OA and then ArmA 2 itself.

I've done anything that was mentioned in any other invalid cd key thread and none of it works. I called Amazon and the representative said he would change my operation arrowhead cd key but that it would take an hour to "go through", but that was six hours ago and it isn't changed. I'm going to PM Placebo my key to see if it's bad.

Not the first person to have this problem and judging from forums I won't be the last. Difference being I didn't get this from Steam, I didn't get this from retail, I got it from Amazon Downloads. I bought this game today for the express purpose of playing DayZ and I find myself quite unable to do that. Spare me the "have you looked at these threads..." because I've been going over the other "invalid cd key" threads for the past two hours and nothing works.
