I bought the Arkham Knight premium edition off G2A in September and the dlc has recently become available on Steam. But... I don't have it. I'm so confused. I have tried looking for a support page but can't find one so I need help! Also I should add that there was a 2.4 GB download so it seems that it should be available.

They probably won't assist, though.
