I just deleted a course I did not need and all the assessments waiting to be marked for all other courses have disappeared!!!! This happened 2 weeks ago and I had to install a backup on a new domain. Now I am having to reinstall backup from 12.15am so all the work done today is gone! Also when i try to delete a file download in a unit and press save the original file download returns! Sort this out, I am sick of this, this plugin is costing me time, money and reputation.
