Activation Key Not Accepted

[Meleemaker 54]

I just purchased Arma II and Operation Arrow head yesterday through Amazon to play Day Z. After a 15 Gb download, I had two activation keys which allowed me to install the game.

Well...I loaded up the six launcher and got all the way into the server lists...I pick one and as it is loading it gives me the vehicle m119a error. From what I understand, its not a big deal and wont affect anything. After that I get in, it gives me a HUGE list of program files(from OA) that are not accepted by "this server. Please install additional accepted keys or remove the listed files"

And I have gotten this error from every server I have tried.
