Close down all items open in relation to Microsoft Office, i.e.Save the copy of the edited document locally on your desktop as a Word 97-2003 Word Document so this can be re-uploaded to Jupix later.
To do this, you'll need to clear the Office Upload Center on your computer. If you're trying to save/upload documents and an error message appears showing Upload Failed, you're still able to save the documents back to Jupix.
