In Ingknife29,
Are you able to select the text in Word if you triple-click it? If not, is it possible that the original PDF was created from a scanned document? If so, the text could be image text, rather than selectable/editable text. ExportPDF converts image text to selectable text by default, but that option can be disabled if you convert the file via Reader. So, I would make sure that you are allowing ExportPDF to perform OCR, and make sure the the correct language is selected for Text Recognition.
Please let us know if you need additional help.
Best,
Sara
