Hi Folks, so I purchased the Blackwood upgrade and in my account page there is a "DOWNLOAD GAME" button, but it looks like it just wants to (re)install the game itself, not necessarily the upgrade. I realize Blackwood doesn't go live until later in the year but I am wondering if I will need to install / update anything on my PC for this, or will the game just know my account purchased it and I'll be good to go ..?? thanks ..
