If you already have a PokerStars Account all you need to do is logon and then click the "More" button in the lower right hand box - then select "home Games" and it should bring up the list.
I got a notice of the game via an email from PokerStars. I still had PlayMoney in my account so it was no problem to register. If you don't have PlayMoney just click the "Free Money" button at the top of the page.
Thanks Roy for trying to get things going again...
