Did you turn on debugging? To turn on debugging, execute window.API.apiLogLevel = 1; before loading the course.

I would help more, but CPXHRLoader.js is a minified file that is unrelated to Simplify SCORM, and is impossible to debug. Seeing what the course is doing before the error would help understand what is happening.
