ajaxtoolkit controls won't allow page to load

Question

I installed ajaxtoolkit to my project and all worked fine.

Suddenly, when I added a new aspx web form and added some ajaxtoolkit controls to it, page won't load. The following error occurs:

"Could not find any resources appropriate for the specified culture or the neutral culture. Make sure AjaxControlToolkit.Properties.Resources.NET4.resources was correctly embedded or linked into assembly "AjaxControlToolkit" at compile time, or that all the satellite assemblies required are loadable and fully signed."

I guess it's something with the .NET framework...

my web config file looks like this:

<?xml version="1.0"?>

Make sure you have added the ScriptManager to your Masterpage - or standard Web forms if not using a MasterPage.

This needs to go inside your <form runat="server"> tag

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
