Please let me know how to fix things so that I can open my programme to finish off 30th September.

Hi Cheryl,

Have you recently upgraded the data file?

The Error (-1,0) indicates a file that has failed the upgrade process.

When a file is being upgraded, the original file is backed up.

Do you still have that older backup?

Do you have ANY backups from a time when the file was able to be opened?
