Hi there,
I have enrolled in a couple of free intro courses, and stared them, but then was distracted with work.
I returned to them this morning and found that they had expired and I can't access them.

Please may someone un-expire the course for me, or explain how I can un-enrol and re-enrol.
My second question: why is there an expiry in the first place? I don't really have time to dedicate a whole day to going through a course, and I've found it's very convenient to run a lesson between tasks
Cheers
Matt
