Cannot install astrid-pro.zip

Hi. I can’t install the astrid-pro.zip, a message appears that style.css is missing.
I put the files from the extracted astrid-pro.zip download from athemes via ftp to the server, but i got the message that the theme is not complete.

I paid for the pro and now i am a bit disappointed

Hi.

SOLVED !

Found a post from july 2017 that astrid-pro is a plug-in and not a theme,

an idea for athemes: can write this information in the beginning of the documentation?
