Could not load file or assembly 'Telerik.Web.Design, Version=2009.3.1314.20

[Yasir Musawar]

Hi,

I was using free telerik version 2009  in my project and recently purchased telerik version 2010. I did not change any web.config setting and it was working fine on my local machine.
But  on the server it is giving me following error in web. config

Parser Error Message: Could not load file or assembly 'Telerik.Web.Design, Version=2009.3.1314.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

on the following line

<add assembly="Telerik.Web.Design, Version=2009.3.1314.20, Culture=neutral, PublicKeyToken=121FAE78165BA3D4"/>

Below is my web.config File code
