If you are able to access your course, but the links within the course to the e-book (or other content) do not work, the first step is to check that your browser has third-party cookies/usage tracking enabled. Please see this article for instructions on how to check your browser’s settings.
If checking/setting your browser’s settings does not resolve the problem, please Contact Us with your name, institutional email address, and the course title, and we will investigate.
