Hi Biagio Di Cioccio Jr,
Looking at your screenshot, I see that you are running the page on the built in server in Visual Studio, rather than running the page in IIS. What I meant was creating a Virtual Directory, making it application, and creating an aspx page to which the virtual directory points.
We still want to help you. If you want, we can perform a GoToMeeting or a Remote Desktop session and make the necessary changes to your web server, so you could run Sitefinity. We are located in GMT+2 (EET, Sofia, Bulgaria) time zone, and are available from 10am till 6pm, business days.
Please let us know if this is acceptable for you, and about your time schedule.
