Problems adding new sites on localhost.

Hi!

I have just installed wordpress and configured it for network on localhost. I am able to create new sites in the superadmin menu. However, when I click on “superadmin”, it says I have 1 site and 1 user. When I click on “sites”, all my new sites are listed. If I try to visit a new site by going to: “http://localhost/blog/olsen/”, nothing is there… There are also no subfolders in my wp-folder named “olsen” (or any other sitename).

What am I missing?
