Two common reasons your course is missing from your account;
1.) Check to make sure your course has not expired. When your course expires, it will no longer be available for you to access it.
You can get your course extended for 1, 3, or 6 months past the original expiration date.
2) Check to make sure you are logging into the right account. Many times students will have two accounts and not realize they are logging into the wrong account.
Call Tech Support and they can determine if you have created more than one account.
