New User's login never reaches the GoTo homepage

I used the admin portal to create a new user in GoTo. I selected the appropriate role and registered her email. When she tries to login, it allows her too, or it doesn't say that she's entered the wrong credentials. The GoTo logo comes up. It's in the center of the webpage "pulsing", getting slightly smaller then larger, but that's it. It stays that way for upwards of 10 minutes. Any recommendations?
