NullReference when execute ConvertToPdf(WordDocument)

When i try convert my docx in pdf file i receive the exception  NullReferenceException.

I'm importing the follow dll:

version: 13.3450.0.7

Imports Syncfusion.OfficeChart
Imports Syncfusion.DocIO
Imports Syncfusion.DocIO.DLS
Imports Syncfusion.DocToPDFConverter
Imports Syncfusion.Pdf
Imports Syncfusion.OfficeChartToImageConverter
Imports Syncfusion.Core

And my code using:


            Dim wordDocument As New WordDocument(filename, FormatType.Docx)

            'Creates an instance of the DocToPDFConverter

            Dim converter As New DocToPDFConverter()

            'Converts Word document into PDF document

            Dim pdfDocument As PdfDocument = converter.ConvertToPDF(wordDocument)

            'Saves the PDF file 


            'Closes the instance of document objects


        Catch ex As Exception

        End Try

The variable "filename" is a full path for my docx. The variable "filenamePdf" is a full path for my pdf file. 
filename = "C:\tempFile\file.docx"
filenamePdf = "C:\tempFile\file.pdf"

What's I doing wrong??

Any help me?
