No Login Click checkout progress bar Errors

Either you fixed in today's update (1.5.9) or it was a modification I did to prevent Address or Shipping to blow up from the Checkout-Login screen. Actually, all option but Payment are blocked. Can you fix it please?

Don't want to give out website to everyone. Sorry gang...

I don't understand your problem.
Please give links/screenshots so that we can understand what's going on.

Sent you a private message with our website in it.

I don't see the problem. I don't have any error on your checkout, even when I click on the progress bar links.
It's normal that they redirect you to the login screen since you need to login before accessing them.
