Can't configurate CKfinder

Hello,

I am in troubles with CKfinder. I already set up CKeditor for use with it and this part succeed. But all functions from CKfinder doesn't work.

I can get into the finder but afterwards everything's stuck.

Here are some details about the project:
path of the main folder: C:/server/htdocs/volkstuinen
path of CKeditor: C:/server/htdocs/volkstuinen/ckeditor
path of CKfinder: C:/server/htdocs/volkstuinen/ckfinder
path of userfiles: C:/server/htdocs/volkstuinen/uploads

To be sure I have attached my config.php (zipped) file to get the errors out of it.
