localhost on windows vista

Hi

I am trying to use my own PC as the localhost. When I go to Scitegic Server Homepage (under Help menu), I get the following error message:

http://localhost:9944
The operating system denied access to the specified file.

Now, the IIS is on, if I type http://localhost I get the lovely new IIS 7 page, however there is something blocking the webpage access through Scitegic (even tough windows firewall is listing Pipeline as exception).
Also, needless to say, but if that doesnt work the HTML molecular table view doesnt work either...

Any ideas on what could it be?

Thanks in advance

Leonardo

PS- My OS is Windows Vista (home premium edition)
