Sims 3 addon purchase not downloading

I just purchased 2 Sims3 addons (Dragon Valley, Monte Vista) but when I go to download them it says that I have to login. I go to login and does not accept the login and bounces me back to the login screen. I can go to the login on the Welcome screen and can login fine. I go into the game and can login fine. Only with the downloads it will not take my login.
