Fail to access web repository

Hi

I tried to create a web repository for www.cnn.com/tech as it is described in the howto-guide in SDN. I did evrything in the guide except the property filter part. When I try to click the link under folder /webrepository (this is my repository folder) I'm getting "Page cannot be displayed" error. The URL is "http://mbisep6:50000/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/webrepository/CNN-Tech/tech"

CNN-Tech is the name of the "Web Site" and tech is the start path.

What may be wrong ?
