LoadRunner and Sitescope Integration Issue

Hello, I got the error when adding the Sitescope monitor configuration in Loadrunner controller.

Parsing error:

Details: host: localhost port:8888 line:11

Reason: DTD is prohibited.

Here is my environment: I turned off the windows firewall. LoadRunner and Sitescope have been installed in the same windows 8 server. I am able to connect to Sitescope GUI with the uername and password at http://localhost:8888/SIteScope. I am using the trial community version of LoadRunner/Sitescope. We are going to purchase both software if trial works well.

Thanks in advance for your input.
