This is a form-based authentication - see recently 
posts about that:

"Form based authentication
You get a login/password HTML page, sometimes with 
some buttons or optional checkboxes
This can ONLY be captured using "ADD URL"/"CAPTURE" 
because the POST request which is used is impossible 
to "catch" with another solution. If you capture the 
page using standard options (that is, enter the URL of 
the page, and mirror it), you'll only get the login 
page, and entering username/password/clicking on the 
login button will put you to an online page.

Tip: Be sure that you defined proper filters (see the 
FAQ), and used proper mirror method.
