[H] Trine 2: Complete Story incl. GM [W] Trine 2: Goblin Menace DLC Key

Hi,

i have got trine 2 complete story as gift but I already own Trine 2.
I just want the Goblin DLC, so it would be a waste of "game", just activating the gift for the dlc.

Has anyone the dlc key left?
I would like to trade my trine2 complete gift for the goblin dlc key plus anything litte
