Why can't I setup Office on my Lumia 920 with WP 8.1?

[WPCentral Question]

Since I updated to 8.1 on my Lumina 920, I can't log in to office to do the setup it is asking for. I have a valid MS acct and can log in with my pc. Any ideas?

Do you have any screenshots or any further description of any errors you're coming up against?
