Unable to create root folder

I've uploaded ckeditor - works fine
trying to get ckfinder to work (firstly) standalone using ASP and keep getting
"Unable to create root folder"

I'm trying to place everything in the /includes/ckfinder/ folder & default userfiles location. Once that's working, maybe I can actually put the files where I want them?

Then I can hopefully integrate with ckeditor, but frustrated at the moment
