Hi, :
Oops! It looks like you tried to access a lesson that is higher than the current level of your membership.

Here’s how it works:
When you signed up, you were automatically placed in Unit One of your subscription.

Every thirty days or so, the system will automatically upgrade you to the next level and give you access to that level’s lessons. You do not have to do anything. When you log in, the system knows when you are due for an upgrade and your next lessons.

If you think the system is wrong, please contact the technical support team at the button below and they will take care of you.

Need help?

    Could you help me to access to all the units in the book one that I paid for?
    Thank you!

      Hi Ivy,
      We were updating the website and we did NOT expect to have any problems. But we did experience a problem, and it is fixed now.
      You should be able to access all the units that you have paid for.

    I watched about 2 videos per day (I love practicing). The RDV website says I cannot go onto 2A. I watched the last 1C video again, hoping to spring a trapdoor, but the website told me I could not go onto 2A, assuming that I had only watched 1 video a day. Can you help?
