problem updating WPBAkery with the7

I bought the7 theme with wpbakery. It was possible to updatate wpbakery plugin for 2 years but now i get the error

An error occurred while updating The7 WPBakery Page Builder: To receive automatic updates license activation is required. Please visit Settings to activate your WPBakery Page Builder. Got WPBakery Page Builder in theme?

Do i need to buy wpbakery? I though it was included.

Bundled plugins do not come with the license to automatically update

Updates are provided by the theme author. Given how experienced the author of that theme is I would expect them to have a fairly up to date copy in the latest theme update. Are you using the latest copy of the theme?
