I forgot to edit my original post, but I ended up just making a new account and it worked. Initially, I had registered an account through the Clementine Launcher and then tried using that in PSU and it didn't work for some reason.
Hi all, I created an account by adding the "_n" to the end of my username, but when I delete that part and try to log in, it says my information can't be validated and I get an error message. Any ideas? Thank you.
