I pre-ordered the Imperial digital edition from Green Man Gaming, and they sent me the early access code. I currently have access to the 5 day head start, but I don't have access to any of the pre-order perks, such as the explorer's pack or Imperial edition perks.
I was told to contact greenmangaming, but what can they do? As far as I understand the explorer's pack perks should already be connected to the early access code they gave me.
