I've just been translating a word doc (docx).
The exported file cannot be opened by either LibreOffice 188.8.131.52, which produces the following error message:
"File format error found at
SAXParseException: '[word/document.xml line 1]: Document is empty
', Stream 'word/document.xml', Line 1, Column 1(row,col)."
or Word 2003:
"There was an error opening the file"
I don't have a more recent version of Word available just now to see how it fares, but I suspect the result would be the same
Please note that both LibreOffice 5 and Word 2003 opened the original document without any problems.
Please create a .ctp package file out of your project via Project > Export > To package... and submit a support ticket with the .ctp package attached. If you did anything unusual such as renaming, removing or replacing the source Word document inside the project's folder or any other project files, let me know in the ticket.
