Looks like pretty robust report to me... nice work! The only thing I can see that seems off is on page two, in the header. It says, "Tickets opened between 03/30/14 12:00AM and 03/30/14 12:00AM." That may be why it is giving no results, since the time window is pulling at that instant and not over the past week. Double check the parameters and if all looks good, raise a support ticket.
Good luck...
