      Hi, I just installed FAF using the wiki (and double checking using the video) and I'm running into an error when I try and log in. I click "Log In with Browser" and it opens a web-page which allows me to log in. It works successfully but when it transfers me back, this error message pops up and prevents me from entering the client. Any ideas? Let me know.
