Hi Rich,

Could you please check whether you have references to the previous versions in your web.config ? Additionally please send us your web.config file so we can check it.

In the meantime I suggest you examine the following articles:
Error: Could not load file or assembly 'Telerik.Web.UI
Updating RadControls for ASP.NET to another version or license
Add/Remove RadControls to the Global Assembly Cache

I hope these articles are useful for you.
