install updates

I received a email saying I have an update

We’d like to let you know that an update to your item 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.

Then I went to my wordpress dashboard and scrolled down to theme update and there was a black box, inside it said:
Last time we checked the token we were not able to connected to Envato:

Following errors occured:

The bottom of the page said: Your current Enfold Theme Version Number is 4.5.2

I don’t understand what I am supposed to do
