If you get a "blocked card" error message, try to sign in to your account to see if you get a message that your account is expired or restricted.
A "blocked card" error can happen even if your library account is up to date and not restricted in any way. We've found that simply re-entering the library card number in Kanopy corrects the issue most of the time.
The document below describes the process for re-entering the library card number. This must be done on a computer or in an app on a tablet or smartphone. If you use a streaming device such as Roku or Apple TV, follow these steps on a computer or smartphone/tablet and it should correct the issue.
