Highend Theme Update Failed and Lost Install

Through WordPress, I attempted to update the Highend Theme. Everything seemed to update correctly. I didn’t see an error message. However, when I go to Appearance > Themes the Highend theme is now a broken theme and there is an error message that the style.css is missing.

When I look at the theme files in the file manager, the only files there in the HighendWP folder is the config file. (see screenshot)

I’m afraid to try to reinstall the theme… will it tell me that the files are already installed? Or will I lose all my work?
