ReportViewer 11 Showing error message

Question

I am using the Reporting Services to generate reports. I have recently upgraded my ReportViewer control from version 9 to version 11. The problem i have is that on version 11 i get an error message

<div id="Viewer_ctl09_NonReportContent" style="height:100%;width:100%; display:none;"> <div style="font-family:Verdana;font-size:8pt;"> <!-- at Microsoft.Reporting.WebForms.Internal.Soap.ReportingServices2005.Execution.RSExecutionConnection.MissingEndpointException.ThrowIfEndpointMissing(WebException e)&#13;&#10; at Microsoft.Reporting.WebForms.Internal.Soap.ReportingServices2005.Execution.RSExecutionConnection.ValidateConnection()&#13;&#10; at Microsoft.Reporting.WebForms.SoapReportExecutionService.GetServerVersion()&#13;&#10; at Microsoft.Reporting.WebForms.ServerReport.GetServerVersion()&#13;&#10; at Microsoft.Reporting.WebForms.PrintCabOperation.CreateUrl(ReportControlSession reportControlSession, ClientArchitecture clientArch, String instanceID)&#13;&#10; at Microsoft.Reporting.WebForms.ClientPrintInfo..ctor(ReportViewer viewer)&#13;&#10; at Microsoft.Reporting.WebForms.ReportViewer.OnPreRender(EventArgs e)--> <ul> <li style="display:inline;">The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version.</li><ul> <li style="display:inline;">The request failed with HTTP status 404: Not Found.</li> </ul> </ul> </div> </div>.

This happens when the report controller first loads, the reports work when i do some filtering. Now this happens when i have the tag ProcessingMode set to Remote. When set to Local i dont have this problem. I am using Sql Server 2005, Reporting Services 2008 R2, and ReportViewer 11.

Has anyone come across this before???? Please help!!!
