    I am having issues trying to add a RadChart to a Sharepoint 2010 webpart control.

    I found this telerik forum post and have followed the directions so far, but there is a bad link in this post and it seems that this is where I'm stuck. 

    I am getting this error from the server:

    Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.

    Snippets from my web.config: 
          <add verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" />
          <add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI" validate="false" />

          <add name="Session" type="System.Web.SessionState.SessionStateModule" />

          <SafeControl Assembly="Telerik.Web.UI" Namespace="Telerik.Charting" TypeName="*" Safe="True" />
          <SafeControl Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TypeName="*" Safe="True" />
        <pages enableSessionState="true" enableViewState="true" enableViewStateMac="true" validateRequest="false" pageParserFilterType="Microsoft.SharePoint.ApplicationRuntime.SPPageParserFilter, Microsoft.SharePoint, Version=, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxxxxxxxxxxx" asyncTimeout="7"  enableEventValidation="true">

    Snippets from my ascx webpart page:
    <%@ Register Assembly="Telerik.Web.UI, Version=2010.3.1317.35, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxxxxxxxxx"
        Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
    <%@ Register Assembly="Telerik.Web.UI, Version=2010.3.1317.35, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxxxxxxxx"
        Namespace="Telerik.Charting" TagPrefix="telerik" %>
    <telerik:RadChart ID="RadChart1" runat="server">
            <XAxis MaxValue="5" MinValue="1" Step="1">
            <YAxis MaxValue="25" Step="5">
            <YAxis2 MaxValue="5" MinValue="1" Step="1">
            <telerik:ChartSeries Name="Series 1" Type="Pie">
                <Appearance LegendDisplayMode="ItemLabels">
                    <telerik:ChartSeriesItem YValue="23" Name="jim">
                    <telerik:ChartSeriesItem YValue="24" Name="pie">
                    <telerik:ChartSeriesItem YValue="19" Name="chart">
                    <telerik:ChartSeriesItem YValue="50" Name="test">

    Is there an updated link to AdvancedSessionState or can someone tell me if something is wrong in what I'm doing?
