This is such an old version of the editor... It may not work properly in modern browsers.
I think you best solution is to download the latest version from: http://ckeditor.com/download
Then use the new client-side implementation that would still work in your old .asp site. It shouldn't be too hard to do. The server side code wouldn't have to change.
If you need help, this is something we could do for you on that page for the price of a premier support ticket ($100)
