Bad cd key, Invalid cd key

[Bad cd key, Invalid cd key]

I have the same problem, also bought retail from Amazon.com. Please can anyone help i want to play Dayz so badly :S!

[I would like to see some private military company add-ons]

I think it would be great if the Dayz team adds on some new stuff from the private military company expension of arma 2. I would like to see thing like Black (armored/or not) suv's, new characters in black company clothing, and maybe also the KA-60 "kasatka" as new helicopter.

Anyone who thinks the same ?
