Can't set login

Just installed, and unable to set login. Welcome screen has login/password fields, but no link to actually establish a login. Tried next to sign in with the apps; no luck there either. For example, Facebook attempt resulted in this:
This page isn’t working is currently unable to handle this request.

You can create an account at the sign-in screen of the application by inputting an email address and password and clicking the “Continue” button (the “Continue” button acts as a “Create Account” button if you do not already have an account).

We did have some reports of sign-in trouble recently, but everything should be back up and running now. Let me know if you continue to run into any issues.
