Problem with FCKeditor connector/uploader aspx pages

Hi,

can someone point me in the right direction or pass along some samples on how to set up the connector.aspx file to allow for file uploads.
I have followed the documentation and various posts, updated my usersfilepath, given rights to the folder, recomplied my assembly, an everything else i found online.

I get a null ref error on this line:
Config.LoadConfig();
in the connector codebehind:
connector.cs


any help is appreciated...i have the default configuration no changes editor lives at root in fckeditor folder and loads properly.

thanks!
