We finally reinstalled last year's program on another computer and copied a backup of data from December before the new update was installed and reentered the transactions and payments.  It has been a job, but at least it works.  I would not recommend using the AR system in the new updated program.  It has been a mess.  The update did all kinds of things that we were not expecting.  It closed old AR entries to a balance forward entry.  It crossed over automatic numbering of balance forward entries and invoice numbers.   I would print an invoice and it would show a different customer and a different balance than the invoice I was printing.
