Server Error - HTTP Error 404 - Not found

Hi all

Started testing FCKEditor for the first time, well tried to start testing it. I have run through the steps to install it including adding the .net component. I dragged a component onto my page, built the site and tried to load the page but I get the following error:

HTTP Error 404 - Not Found.

Here is my page code:

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="FAQCreator.aspx.cs" Inherits="FAQCreator" Title="Untitled Page" Theme="BlueChrome" %>

<%@ Register Assembly="FredCK.FCKeditorV2" Namespace="FredCK.FCKeditorV2" TagPrefix="FCKeditorV2" %>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">
<asp:Label ID="lblHeader" runat="server" Text="FAQ Display"></asp:Label>
</asp:Content>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

   <div runat="server" id="faqDisp"  >
       
       <FCKeditorV2:FCKeditor ID="FCKeditor1" runat="server">
       </FCKeditorV2:FCKeditor>
   </div>


</asp:Content>
