Error when using latest internal build

[Dennis Chipps]

I installed RadControls for ASP.net AJAX Latest version 2010.1.415    and found that they could not be used with the asp.net ajax controle toolkit.  I downloaded the latest internal build and created a tab in the toolbox and imported the controls.

I am getting the following error.

Error Rendering Control - ScriptManagerAn unhandled exception has occurred.
