Just clicked the confirmation link that appeared in my email. Had to accept some terms and conditions. I can't actually get insurance this way because I already have insurance through my state's exchange (I pretended I lived in Maine for this test account, since my state doesn't use healthcare.gov). But my profile page loaded fine. This series of steps also took less than a minute.
Anyway, sorry it's not working for you, if you're really trying to get insurance.
