Web Tours Sample application in Loadrunner 11.0 is not working

I am trying to use the sample web application in the evaluation version of Loadrunner 11. But to my surprise the sample flight application is not getting launched at all. When I tried to see the content of web server startup script, the web server is not coming up at all. Please guide me if there is a patch from HP on this issue. Else if you have any other solution also helps me lot.
