I have trouble when trying to convert PDFs to Microsoft Powerpoint format. Despite multiple attempts (including restarts and trying for different documents etc.) I receive the error message "Conversion Failure" stating that something went wrong when uploading the file. Does anyone know how to solve this problem?
