download this to your desktop,
http://www.swicago.com/funjunkie/hosts.bat
then right click it and choose RUN AS ADMINISTRATOR. Then it is done. The site is back to normal. Big Mahalos to SwiCago for dealing with me in PM's for 3 days to figure this out and Dragon for dumbing it down for my less than computer savvy ass.
If you want to do it manually without the download (which didn't work with me, Mabey because of Vista)
Go to your start menu
Click on "My Computer"
Click on "Local disk C"
Click on "Windows"
When it says that these files are hidden, click to show all files.
Click on "System 32"
Click on "Drivers"
Click on "Etc"
Click on "Hosts"
When it asks what program to use to open Hosts with, choose Notepad or word pad and click "OK"
Copy the info that Swicago wrote in his post, and paste it underneath the example and local host.
