importing and indexing failing

I am trying to import a very large scanned document. I have scanned it as a tiff and then put it through Omnipage OCR. The document is then saved as a word document. I can open it in Word and edit and search it but when I try to either import it or index it in DTPro it does not work and I get the message “failed” - am I missing something? I am starting a large research project and I would like to get the process correct. ( the word document is 16.3mb) Thanks

Are you able to open the document in TextEdit?
