Hi
Thanks for your request. Aspose.Words throws an exception when I try to open the document you have attached. I created new issue #7944 in our defect database regarding this problem.
It seems the problem occurs because one line is missed in the [Content_Types].xml
<?xml version="1.0" encoding="utf-8"?>
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
<Default Extension="xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml" />
<Default Extension="rels" ContentType="application/vnd.openxmlformats-package.relationships+xml" />
<Default Extension="gif" ContentType="image/jpeg" />
<Default Extension="bin" ContentType="application/vnd.openxmlformats-officedocument.oleObject" />

<Override PartName="/word/fontTable.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.fontTable+xml" />
<Override PartName="/word/document.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml" />
</Types>
After correcting the file I managed to reproduce the problem with DrawAspect and created new issue #7946 in our defect database.
I will notify you as soon as these issues are fixed.
If you open/save the original document using MS Word, Aspose.Words will not change DrawAspect.
Best regards.
