I bought Deluxe on Steam in a very quick decision, and I was thinking that was the Supporter edition. I'd like to upgrade ASAP. BTW, I got all titles since OFP1, but have been away from playing since ArmA I.

Sorry if this is not the right place to make this question, but I haven't found other that seemed best, so, please, could someone help me with the question above? I mean, I bought a Deluxe Editon from Steam, and now I see that there is a Support edition being sold, and I'd like to upgrade my subscription to this one. How can I make this? TIA Silvio
