If you think it's a problem with the dns you can try the following.
Open up cmd. I don't know which version you have so either go to Run > type in cmd or search in the Vista search box at the Start menu. For Vista you'll need to right-click and go to Run as Admin.
Just wait a little and then keep trying over and over. When I first downloaded Fiesta that happened but now it is normal. I dont know why it happened but after enought times of trying to log in, it worked.
