I already have the game installed, I downloaded it when I bought it last year. Like I said earlier my problem is that I cant log back into my account on the vintagestory.at website. I'm able to log in on the game and play it just fine, but I cant log in on the website.
You need a forum account to login to the website, it doesn't use the same email/password you use to play the game https://www.vintagestory.at/register
