I ran into a similar problem today.  When I try to email statements I get a message that says "Warning. Mothing to print. No statements were created. there are no outstanding invoices. credit memos for the date range you selected." This is clearly false.  If I choose to "print" the statements it generates 22 statements for customers with a balance. It is only when I choose to "email" the statements that I get this message. I have been emailing statements from QBDT for many years and never had this issue.  I think that Intuit wants to force us to switch to the online version so they are letting the DT version go to pots.
