A couple of obvious things I see: there are lots parameters missing in the data
you're sending in the code, such as "token" and "bmlUrl"; the site is
sending a cookie that you're not sending back; the data you're sending is
entirely URL encoded, which is probably shouldn't be; and you're doing a GET,
not a POST. Take a look at what a browser sends for the login using something
like the Firefox's LiveHttpHeaders plugin or Chrome's built-in developer tools,
and compare that to a debug log of what your program sends out. You'll quickly
spot differences like this.

I'm not even sure what you're saying here. What is "filling in the form" in the
context of a libcurl-using application? An HTML form is a template used by a
browser to send an HTTP request to a remote server. If the user fills in the
form on his screen, the browser will send that data to the serve in the format
specified in the FORM element.

Take a look at http://curl.haxx.se/docs/httpscripting.html for a discussion of
some of the issues at work here.
