Content: Why can’t I revisit a course I previously completed?

It is not possible for an Administrator to manually reset an end users progress on a course.

     1. SCRIPT: Some courses are designed to prevent you accessing them after they
         are completed. It would appear that this is the case for this course. 

     2. ACTION: If the user feels that they should be able to access the course 
         content after it is complete then you should escalate to the content owner.
