FIXED IT. What you need to do is sign into your netflix account in Chrome or Firefox and navigate to Account --> Devices --> 'Access and devices'. You'll see a list of everything that is currently logged into Netflix. With the exception of the one marked "current device", locate anything that says "Web Browser" and click "Sign Out". You can leave your TV's, Roku Devices, Xboxes, and other hardware devices signed in. There is a button at the bottom that says "Show More", be sure to click that to show everything. Sign out only the ones that say "Web Browser". You'll notice there are probably a lot of them. Once they're all signed out, start Steamfab and you can sign into Netflix successfully.
