Load course using Commerce Product

Hi, Is there any way to programatically load the course object(like node_load, commerce_product_load etc.) on Opigno? I already check the module inside the distribution but I haven't found it. One more thing, the forgot password of this site is not working properly. After I change my password it doesn't really changed on database(not sure what is the problem), I guess the drupal_render_children is missed out? Thanks!
