Zubin Music Missing Demo Content

Hi I've installed and activated the Zubin Music Theme and the plugins Catch Themes Demo Import and Essential Content Types so I can import the demo content. When I go to Catch Themes Demo Import in my Wordpress Admin section, I get the message "There are no predefined import files available in this theme. Please upload the import files manually!". I searched the forum for possible solutions, like a hard refresh (ctrl+F5), but nothing seems to work. Can you please advise or send me all the demo content files so I can upload them manually? Thanks! Em
