Problems accessing Live Chat for secondary breast cancer

I’ve created an account and registered to participate in live chat.  I’ve received a link to join but it won’t permit me to join.  I’m being asked to sign on and am using precisely the same user name and password as I do to get in here but it’s saying it’s invalid.  What’s wrong with it? 

Hi Susan B

You can access the live chat here: breastcancernow.org/information-support/facing-breast-cancer/secondary-metastatic-breast-cancer/live-chat

Is that the page you visited?
