asking a 2nd time, CKEDITOR.. not working

[Shane78]

asking a 2nd time as no one replied 1st time and i see that there are a handful of other zenners that have the same problem and no ones answered them either.

downloaded CKeditor, followed instructions but nothing appears in the admin.

when i go to a page that uses an editor, the plain text and HTMLeditors appear ok, when i select CKeditor from the drop down list, the area where the editor shopuld appear is left blank.

i have downloaded 3 copies from the ZC downloads area,
i have uploaded each 3 times.
i have checked my webspace the files are in the same locations as the .txt file says
i have used winmerge to check the folder structure / files in the download and of those on my server and they're 100% the same.

so.. where is the CKEditor?
