oncemorealoft,
Thanks for the share! I understand exactly what you have explained as it happened a few weeks ago to my wife. Also a Uni student and an assignment that was a month in the works was lost in the same way....she was working on a self emailed copy that just disappeared in the same way you described. Fortunately, when she is not around I pop in and back up all her work in 3 different ways so only 2 days work was lost. I spent hours trying to retrieve what I knew had to be there but to no avail!
