I received the same notification a few weeks ago, and had not been aware of my free trial. IdeaFit TV is an extensive library of videos that includes lectures and sample classes by various presenters. It is a paid monthly subscription. You should be able to go to IdeaFit TV and view the videos for the next few days. After the trial period, you cannot access the videos without paying for the subscription.
Enjoy the trial the period while you can–the library is a great resource and has lots of great information on many subjects.
Hope this helps.
