PDFViewer in Aspose.Pdf.Kit

I am using version 3.3.0.0 of Aspose.Pdf.Kit and in our development environment (Windows 2008 R2 Standard 64 bit) it works fine. When attempting to deploy to our production environment (Windows Server Enterprise SP2 64 bit) I get an error "pages are corrupt or too many pages" when invoking the OpenPdfFile method. In both cases we are running version 2.2.50727 of the .Net Framework. Thanks for your help.
