Yes, I have a HTTP-Server (Apache) and it works.When I type in "localhost" in
my webbrowser, I can see my site :-).

It tells me that either the website does not exist or my proxy settings are
not correct, but I havn't entered proxy and the site exist T.T...

WinHttrack scans only 4 files and stops than. It displays just the scan of
"localhost/" and "localhost/robots.txt"
