Weekly report e-mails show no activity

My NOF is working fine, blocking sites as requested and logging all the activity as requested.  However, at the end of the week when I get the weekly e-mail report of my kids' activities, every e-mail shows no "Time Usage" or activity whatsoever for the previous week.  When I log onto NOF I can see a log of all the sites and activites and I get e-mails telling me when a child has exceeded his/her daily time limit.  But the weekly e-mails claim the computer hasn't been used!

 

When I first purchased NOF about three weeks ago, I got that week's report correctly, but since then the last two reports showed no activity.  These weekly summaries were the principle reason I chose to purchase NOF.
