Once you have completed your enrollment and have received your email receipt you should see your purchased course listed on your homepage when you log in. If you do not see your purchased course, it could be that you accidently set up more than one user login and could be logged into the wrong account.  
Check your enrollment email that you received around the time of your enrollment. If you are still unable to access your course, please contact support by phone (858) 329-0999 or by email [email protected].
