Spire.Doc does not load some of the content of the docx document. In the attached document, it does not load entire body section (3 paragraphs). When I save it as PDF or any other format or print it, those paragraphs are not rendered. It shows <<body>> tag instead of that.
Code
Spire.Doc.Document doc = new Spire.Doc.Document();
//Load word document
doc.LoadFromFile(@"C:\temp\letter.docx", FileFormat.docx);
ToPdfParameterList topdf = new ToPdfParameterList();
topdf.UsePSCoversion = true;
doc.SaveToFile(@"C:\temp\letter.pdf", topdf);
