XXXSCORPXXX

I purchased a copy of ARMA II OAH back in October from a retail games outlet. I've been holing off the install till now due to Vid card upgrades & new OS. Problem is its saying that the CD Key provided on the back of the booklet is invalid. But it is the one that came with the game. Apparently this is a "non refundable game" according to EBGames which is where I purchased it from. Any sudgestions??

THanks for the swift responce. Ill try that.
