The list you are trying to access has been marked private and can be viewed by invitation only. If you have been invited to the list, there are couple of ways to access it:
A) Click on the link in the invitation email you received, or
B) Sign in using the invitation address to which the invitation was sent. (And if you use multiple email addresses, it easy to add email addresses to your account so you can access all your invited lists in one place).
one sec please...
