Problem with BarcodeReader.Timeout


I'm trying to read all barcode Code93Extended in a PDF.
My method works fine with a lot of PDF but I Have a problem with 2 files.
Calling "barcodeReader.Read()" stucks, Method doesn't return. My application hangs on this method.
I set Timeout (in milliseconds) but doesn't work.
I use Aspose.Barcode 5.0 (I can't upgrade it).

Help me please. Thanks!

Private Function GetBarcodePDF() As List(Of String)
Dim listCodes = New List(Of String)
' Set Licence.....

        ' bind the pdf document
        Dim pdfExtractor As Aspose.Pdf.Facades.PdfExtractor = New Aspose.Pdf.Facades.PdfExtractor()

        ' set page range for image extraction
        pdfExtractor.StartPage = 0
        pdfExtractor.EndPage = 1

        ' extract the images

        ' save images to stream in a loop
        Do While pdfExtractor.HasNextImage()
            ' save image to stream
            Dim imageStream As MemoryStream = New MemoryStream()
            imageStream.Position = 0

            ' recognize the barcode from the image stream above
               dim     barcodeReader = New Aspose.BarCodeRecognition.BarCodeReader(imageStream, BarCodeReadType.Code93Extended)

            barcodeReader.Timeout = 2500

            Do While barcodeReader.Read()
            ' close the reader

   GetBarcodePDF = listCodes
    Catch ex As Exception
        m_exception = ex.Message
    End Try
End Function
