Code 3 means 'Path not specified'.
This could occure because the file path for the export option than you are using
does not exist.
Please check for the file path it is trying to export to in
'[SETUP -> PROPERTIES -> FILTERS & DEFAULTS]',
in the 'Enable Local Front Office' section under 'Output File Path'.
Now use for example 'My Computer' to navigate to this file path to make
sure that it does exist.
