Breadcrumbs for Woothemes' Sensei

Hi, We got this plugin installed called Sensei (by Woothemes), which is a learning management system with this structure: Post_type => URL Examples {Course} => domain.com/courses/course-name {Lesson} => domain.com/lessons/lesson-name {Quiz} => domain.com/quizzes/quiz-name We also got your breadcrumbs activated on our website and would like to show breadcrumbs like this: For course pages/posts: Home => [courses] => [course-name] For lesson pages/posts: Home => [courses] => [course-name] => [lesson-name] For quiz pages/posts: Home => [courses] => [course-name] => [lesson-name] => [quiz-name] With the following linking structure: Breadcrumb Title Breadcrumb Link Post_type [courses] => domain.com/courses [course-name] => domain.com/courses/course-name <= {course} [lesson-name] => domain.com/lessons/lesson-name <= {lesson} [quiz-name] => domain.com/quiz/quiz-name <= {quiz} Unfortunately, I can’t get this to work properly for a while now. Can you please help me? Any response is much appreciated, thanks in advance! http://wordpress.org/extend/plugins/rdfa-breadcrumb/
