Can't play the game

[BeholdAPaleHorse]

So a few days ago I purchased the game on Steam so I can play with my friend. When I launched the game I couldn't register, https://imgur.com/a/TuILPmA this immediately popped up after trying to do so. I logged out of Steam, then relogged to see if its going to get fixed, well it was not. Then I restarted my PC and quickly logged into Steam and launched the game and it was working. The next day I went through the same process to be able to play the game. Today I restarted it again, but now it just wouldn't let me play at all... I launch the game from my Steam Library, and when I'm in the menu I click on Log In through Steam and this message pops up again.

I have registered with my email, it wouldnt work that way either

I have an internet connection

I'm not offline or hidden on steam

I do not have steam family share or whatever activated

I literally have everything that is required...


I don't want to refund cuz I played 8 hours in under 1,5 hours (when it somehow let me to) so please... help...

You could try with logging in using your username & password, this has the same effect that the "login with Steam"-button.
I am currently unsure why this message would pop up.
