    There is an reported issue with the PDF file that is generated along with the uploaded file at Dropbox, the filesize is 0kb which results to this error message upon opening it. A ticket has already been created for our developers to check.

    Sorry for the inconvenience this may have caused.

    Hi Steven,

    That's a great tool! You help so much, I have downloaded that and it works like a charm on my end. Hopefully, that will help the others as well.
