Sharepoint 2010 with RadChart issues

[Jim]

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: 
    <httpHandlers>

    </httpHandlers>

            </Items>
        </telerik:ChartSeries>
    </Series>
</telerik:RadChart>

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