I am having the same problem. Getting stopped at the page that asks for your date of birth. The error I keep getting is "We are unable to validate your identity. Please check your information and try again. If you need assistance contact Customer Service at 866-645-3111." The number is a robot with no option to speak to a customer representative. If you wait long enough, you'll get "Sorry you are having difficulties. Goodbye!" It's almost funny.
