Enfold Update 4.02


I can not update Enfold 3.85 in 4.02
I received the mail of information asking me to connect to my account

(We’d like to know what you’re getting.) Enfold - Responsive Multi-Purpose Theme by Kriesi is now available in your Downloads page.
Remember: you need to be logged in to download the update.
I do not see the update on my envato account.

On the other hand when I go on my wordpress admin on the directory Envato Market, I have an error message that tells me that the directory is already installed

Installing Theme: Enfold 4.0.2

The installation of the theme failed.

What should I do to update my theme?
