Go to http://www.mathzone.com/ and sign in with your email address and (Mathzone) password.
Click your textbook, then "Course Management".
Enter your Student section code in the box in the lower right corner and click "go".  This will place you in the right course and section.  Remember to include the hyphens when entering the code.
