Hey guys, now i installed steam and i did everything til it wanted my activation code, i typed my code in and it said this exactly "Duplicate product code, the product code you've entered has already been activated by an existing steam account, and is therefore invalid. your activation of napoleon: totalwar retail has not been uncompleted" I've already went to the store i bought it from and asked for a new copy and this new one said the same thing... i dont know if im doing something wrong. help would be very nice =)
