I preordered Endwalker on Steam, but haven't tried playing it until today to wait until queues were not so high. When I went to log on it told me I had to register my CD Key. I pulled it up on steam and entered it into the prompt on the launcher. It told me the key was in use. I went to the mogstation and tried it there. It also told me the code had already been registered. I have tried so many ways of contacting support and everything is automated and seems to loop back around in circles and I just really need some help here. What can I do? Steam doesn't even let me refund DLCs so am I just out of luck here?
