practice session

I just now subscribed to PRO so I could conduct small webinars. I'm interested in using the practice session feature. However, after I log in and select webinars, instructions say to then select Start a Webinar. But this selection is nowhere to be found. What am I doing wrong? Does it take 24 hours for the application to recognize me as a paid subscriber? My account already says that i am a paid subscriber. Could sure use some help. Thanks!
