I bumped into this and well, I tried again and succeeded. However if this was on a domain or you are using that email rather than local login you could run into that issue.
Here's a note on local login on 8.

In short, you didn't reveal your login choice here.

Win 8.1
I created a new user account with administrator
privileges as usual, but the new account does not show when I log off or try change accounts. It also isn't listed on the upper right corner of the start page.
Basically even though I see it in other accounts through the settings menu, I can't switch to it.If I go to disk C/users it's not listed.
I turned on Guest Account and also I can't choose it.
Could someone please address this issue..
