SharePoint Services 3.0 Can’t Create New Site

I have messed around with Windows SharePoint Services 2.0 for awhile and I was looking into the new 3.0 version. I can’t even get a site created on it. I try to go to the Site Actions tab but I click on it and I get no response. So then I go to the sites column and try to create a site there, and it will let me put in all of the information but when I go to hit the Create button it doesn’t do anything at all. Is there something I’m doing wrong? I have the proper permissions to make sites?
