did you check your registry to see if you are blocking the site in there? Go to START --- RUN---- type in "regedit" and that will open your registry. Then go to EDIT "Find". Type in "xat.com" and see if it comes up anywhere in your registry. If it does, it's possible that you are blocking the site in your registry. I use the registry to block some sites, too. If so, you can delete the entry "xat.com" if it exists but be careful and you might want to run it by someone before doing it .....or also, backing up your entire registry before doing it so you don't screw yourself.
