.Net - Could not load type from assembly

Could not load type FredCK.FCKEDITOR from assembly FredCK.FCKeditorV2, Version=1.0.1796.3988, Culture=neutral, PublicKeyToken=4f86767c9b519a06.

ok, I'm reaching here...i get this message when integrating into a asp.net webform using this on top of my page:

<%@ Register TagPrefix="FREDCK" NameSpace="FredCK" Assembly="FredCK.FCKeditorV2" %>

and this where I want teh editor to show up:

<FREDCK:FCKEDITOR id="FCKeditor1" runat="server" CanBrowse="True" height="500px" BasePath="../fckeditor/" CanUpload="True"></FREDCK:FCKEDITOR>

I played with the basePath, I deleted and re-installed .net framework and installed the latest service pack. Nothing works...Help!

Please and Thank you
