I have build error using Visual Studio Express 5.0.  I get the error Unknown server tag 'CE:Image Editor' when I try to build.  It does not like the line:

 <CE:ImageEditor id="IE1" runat="server" Width="500" Height="380"></CE:ImageEditor>

Not sure that the problem is.  Do I need to alter the provided code for CuteEditor.net?

 

Any help would be great...  Thank you!
