Can't watch Netflix movies using windows media center, but works in IE and on PS3?

When I try to watch a movie using windows media center, it shows I am logged in. It takes me to the movie selection screen. When I select a movie, it takes me to a log in page. From this page I am not able to log in. When I click in the field to enter my user name or password, it won't accept any commands from my keyboard. Netflix works fine using IE and even my PS3. I really like using media center because I can use the remote control to watch the movies on my PC rather than having to get up and use my mouse. Any help would be appreciated. I have tried logging out and back in.
