I really love Mafia II, its one of the best games of all time i've played, and with that i collected almost every DLC it offers (including the bad ones).
And to complete this, i whould only need the Digital Deluxe Edition, but the thing is, i aleady own the normal (vanila) edition, and when trying to buy the Deluxe edition on Steam, it says that i aleady own the product.

Is there anyway i can obtain the Digital deluxe edition? I whould really love to see an way i can buy it to complete my collection!
