Either Registration Key Error, Or No License Error (Steam)

When I start the game anywhere (including inside Steam) I get send to the blue welcome screen and have to enter my info. After I did all of it I get the message that I need to "enter my registration key" which gives me the message that the key has already been used (of course).

What I noticed is that eversince Steam got linked the ID field is greyed out and bears my Steam ID rather than my Square ID

When I start the game as admin I can actually type in the ID myself. When I enter my Square ID and password I get told that I have "no licenses to play the game" which is just plain wrong. When I log into Mog Station it clearly states that I have them.

I tried:

• Fresh install
• Change values under documents which did enable me to get the usual white launcher with the adds, however the error messages stay the same
• I contacted support, unfortunately to no avail as of now
• Change my password when asked to do so after the "suspicious activity" error
• validate the integrity of game files
• tried to delete the etc folder - Enter Timmy´s dad: If I had one!
• asked on Steam forum
• asked on FFXIV Subreddit
• turned my PC on and off
• checked that my Steam profile name only has plain letters - it does
• cry
• asked for help on the official Twitter in japanese

I am stumped as to what I could still do at this point. Any help is greatly appreciated:)
