Cannot Download Create A Pattern tool for Sims3 PC

I have been trying to download the create a pattern tool but to no avail at this link http://www.thesims3.com/game/tools/pattern and through, of course the drop down menu as well. I have read through the user license, clicked the little square box and chose the pc download. It asks me to sign in which I'm already signed in, it signs me out, I try to sign in and it tells me invalid login.... or I get  Oops page???? But if I click on the sims 3 logo, I'm singed in... Help appreciated.
