PdfHelper return Objektreferenz nicht auf Umbraco auf eine Instanz gesetzt 7.4

Question

Ich habe PDF Creator auf Umbraco 7.4 installiert. Wenn ich den Rasierer Beispiel Vorlage testen verwenden, kann ich eine PDF-Datei erstellen, aber wenn die PdfHelper Verwendung gibt es

System.NullReferenceException: Object reference not set to an instance of an object. 

Line 3: @helper Start() { 
Line 4:  <!-- Start Root --> 
Line 5:   @Html.Raw("<fo:root xmlns:fo=\"http://www.w3.org/1999/XSL/Format\" xmlns:ibex=\"http://www.xmlpdf.com/2003/ibex/Format\">") 
Line 6:  <!-- End Root --> 
Line 7: } 

ich eine neue Vorlage erstellt haben:

<?xml version="1.0" encoding="UTF-8" ?> 
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage 

@{ 
    Layout = null; 
    //Response.ContentType = "text/xsl"; 
    //Response.AppendHeader("X-Pdf-Render", "true"); 

    // -- Uncomment this to force the browser to download the PDF. 
    // Response.AppendHeader("X-Pdf-Force-Download","darren.pdf"); 
} 
    @PdfHelper.Start() 

    @PdfHelper.MetaData(@CurrentPage.Name, "Darren Ferguson") 
    @PdfHelper.LayoutTwoColumnA4() 

    @* For ecnryption and password protection there is a: 
     PdfHelper.Secure() and PdfHelper.Secure("userPass", "ownerPass") helper *@ 

    @PdfHelper.StartBody() 

     @PdfHelper.StartArea("header") 
      @PdfHelper.Block(@CurrentPage.Name, "Arial", "23pt", "#3399ff") 
     @PdfHelper.EndArea() 

     @PdfHelper.StartArea("body") 

      @Pdf.RenderRichText(@CurrentPage.BodyText) 

      @PdfHelper.PagerBlock() 

     @PdfHelper.EndArea() 

    @PdfHelper.EndBody() 

    @PdfHelper.End() 

Und das gibt nur die oben genannten Fehler .

Die Protokolldatei enthält diese:
