Good morning, @tlarklark Welcome to the Canvas Community. Thanks for posting your question. I am sorry to see that you no longer have access to your courses. Unfortunately, the majority of Canvas Community members here would not be able to help with this situation because we do not have access to your school's Canvas environment. The best advice I can give you is to reach out to your school's local Canvas administrator to investigate this issues further. Your school may have a page on their website dedicated to Canvas resources for students, so I would suggest you start there. Or, if you can contact your instructor, that would also be an option. Also, please make sure that when you are logged in to Canvas, click on "Courses" on the left-hand navigation menu, and then choose "All Courses". If you do not see your courses listed there, then you'll want to reach out to someone at your school who should be able to help. Good luck, Tanya!
I'm not sure if you realized it or not, but you posted your question to the global Community of all Canvas users. As such we don't have access to your Canvas environment to be able to truly troubleshoot this issue for you so I will do my best to give you things that it could be.
I would also recommend reaching out to your schools help desk, student advisor or Canvas Admins for additional assistance as they have access and knowledge of how your schools Canvas is setup.
