I also am having problems resubmitting files. My problem is that I need to update 2 events as I had not registered Reckon with the ATO. Once I registered and submitted the files again they have all gone over perfectly. However the first 2 Pay runs that I did on 3/07 and 10/07 have disappeared from the saved files and Reckon is only showing the last 4 pay runs. How do I see all pay runs please so I can recreate the STP files.
