new user - unable to "Complete Membership Setup"

I'm brand new here. Just signed up yesterday.

On the "My Account" page, I'm told that to "get more from your membership" I need to "complete membership setup" ... I click to get started and I'm asked a few questions and then click "Next" to get to the next page in the process.

I've tried this *several* times, and it will eventually just stop responding. I hit "next" and it sits on a blank page. I've tried different browsers and different devices.

I can't get through the wizard. How I finish setting up the membership?
