Thank you for additional information. As I can see you use the old version of Aspose.Words (7.0.0). Please check the version of Aspose.Words. To check version of the library, right click on the dll, select Properties from the context menu, then select Version tab. You will see File version.
Just replacing files in the bin folder is not enough, you should remove old reference from your project and add new reference to new dll.
Thank you for additional information. I have tried one more time with your document, but still cannot reproduce the problem on my side. Do you perform some processing of the document or just convert it? Could you please create a simple application, which will allow me to reproduce the problem on my side?
