Purchase code not activating Enfold to update

The website was originally built using Enfold child theme. When moving away from the company that built the site, we had to buy the theme in order to have the ability to keep our theme updated. When inputting our purchase code, I keep getting this message:

“Last time we checked the token we were not able to connected to Envato:

Following errors occurred:
