Hi

I've set up a little crystal report which just lists some data from a table. No parameters etc

I've created a small program to run it . (below)

using System.IO;
using System.Net.Mail;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.ReportSource;
using CrystalDecisions.Shared;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
ReportDocument report = new ReportDocument();

report.Load(@"C:\Nicksworkspace\MMU_Reports\testreport1.rpt");

report.ExportToDisk(ExportFormatType.PortableDocFormat, @"C:\Nicksworkspace\MMU_Reports\report.pdf");

When I get to the ExporttoDisk I get this

System.TypeLoadException was unhandled
Message=Method 'ISCREditableRTFExportFormatOptions_reserved5' on type 'CrystalDecisions.ReportAppServer.ReportDefModel.EditableRTFExportFormatOptionsClass' from assembly 'CrystalDecisions.ReportAppServer.ReportDefModel, Version=11.0.3300.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' is overriding a method that has been overridden.

Any thoughts on what this error message is trying to tell me.

Thanks
