Trying to create a new Voxalot account

[BigTex]

Hi,

I have a Voxalot account and now I'd like to set on up for my wife. We use the same computer. When I go to Voxalot - Home, it automatically signs me in. So, signed in, I clicked "getting started", and "subscribe now". I filled in the page, it sent an email to her yahoo email account, and we clicked on the link, but it filled in my existing user information in the setup page instead of hers. I tried clicking on the link again, but got an "Unable to confirm registration" error message. Do I need to sign out of my Voxalot account before creating one for my wife? If so, how do I do this? If not, what did I do wrong?
