So, right now I'm sitting on a code for this game as I rebought it back on early access so I could well, get early access.

I got the early access, but because I was a 1.0 player (not legacy) It seems I can't add the game code as I already have the game, so now I've only got 10 days left and I assume an extra copy of the game.

Is there any way for me to use that code to add the free 30 days?
