HI folks,

I have a .net application (vb.net) and I'm using the ajax control toolkit. It works fine on my production machine but when I upload it to the host (fasthosts) i get this error:

Could not load file or assembly 'System.Web.Ajax, Version=3.0.31106.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies. The module was expected to contain an assembly manifest.

Here is my web.conf file. Its very simple:

<system.web>
    <customErrors mode="Off"/>
    <compilation debug="true">
        <assemblies>
            <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
