Enfold-v3 : Hosting provider said to update Enfold. I need help.

Hello,
I do apologize if I’m asking for something not provided here. I’m not very familiar with this, but my website is down and my hosting provider said it’s because I needed to update enfold-v3 and that would fix it. I’ve read how to update the files, but I’m not seeing enfold-v3 in the theme I just purchased. Any hints or direction would be much appreciated. This is the error that my hosting support sent to me to say I needed to update enfold-v3.
