Created Unassigned: Could not load control AjaxControlToolkit.HTMLEditor.Samples.Lite [27492]

I have a problem with HTMLEditor.Editor with the version of July Version 7.0725 .NET 4.0
With previous versions everything was ok!

With or without AjaxControlToolkit.config

<controlBundle name="HTMLEditor">
<control name="HTMLEditor"></control>
</controlBundle>

There is the full exception stack:

[Could not load control AjaxControlToolkit.HTMLEditor.Samples.Lite. The script reference(s) of this control was not loaded correctly. If AjaxControlToolkit.config is used, probably this control is not registered properly.]

[Exception: Could not load control AjaxControlToolkit.HTMLEditor.Samples.Lite. The script reference(s) of this control was not loaded correctly. If AjaxControlToolkit.config is used, probably this control is not registered properly.]

Help Me Please.
