I'm trying to link my steam account but it says it's already linked to another user, so I need to unlink my steam account from that other user that I don't know which one it is, to be able to get the Endless Dungeon game and the DLC for free. The only thing that comes to mind is when Endless Space 2 was given away for free on the Company of Heroes website which also used games2gether and I had to link my Steam account there, I unlinked it from that account but I still can't link it lo here, also tried to login with that account details here but no data. I need help please.
