I just double-checked my interface settings in Paydirt. They are:
G/L Interface: Adagio 8+, currency code DOS
Chq rec interface: Adagio A/P 8.0+
Jobcost interface: Adagio J/C 6.8B+

I do want to figure out why the interface has stopped working, but I don't need to made this particular batch importable, as this is a test workarea.

Thanks.
