Saving to PDF file throws exception


I’m using Aspose.Words trial version to modify a Word document (docx) and saving it as a pdf file. This causes an exception “System.InvalidOperationException: Stack empty.”. Saving as a docx file works fine and I can open the document in Microsoft Word.
Were could I look for solutions?


Might note that the PDF file is created but can’t be opened as it is corrupted.

If I open the docx file then there is not problem in saving it as an PDF file.
