Safari 4 Not Connecting to the Internet/Server?

I just downloaded Safari 4 for Windows (I'm on vista) and after installing it whenever I open it up it doesn't connect to the internet. Opera, Firefox and IE connect to the internet fine but Safari just says "can not connect to server'. Please help me, I tried reseting, reinstalling, rebooting and reseting my wi fi. Any help would be appreciated thanks.
