Hi Kevin,

If you are referring to Adagio Invoices for your 'invoices program', then all these data files have a prefix of 'QI' in the data directory. If you are getting a 'data doesn't exist' message, then specifically the data file 'QIGLOB' is not there, though there could be others missing too.

If there are any data files starting with 'QI' and a file extension the same as your accounting data, these have been deleted by mistake and you should restore them back (from the recycle bin).

Let us know what you find.
