If you purchased the TOTEM, it does expire after the National Occupational Therapy Certification Exam (NOTCE), please contact exam@caot.ca. For all other e-Books, contact publications@caot.ca

I get an error telling me to turn off my screen capture.

Lock Lizard is designed so that you cannot take screen shots of the publications. Windows has a program called One Note that runs in the background of some version without you necessarily knowing about it. To turn it off, click ctrl + alt + delete. Open the task manager. It typically opens the tab at the top for applications, open processes and find One Note and turn it off.

If that does not work, contact publications@caot.ca

I get an error message indicating document access failed.
