Class ‘td_css_compiler’ not found

Hello,

We currently have the Newsletter theme version 8.5 installed.

So we purchased the updated version of the Theme Newsletter 12 on ThemeForest.

I downloaded the Newspaper-tf file, extracted Newspaper.zip to a folder called Newspaper then uploaded it to: /wp-content/themes/Newspaper/

The site broke and we have errors like:
PHP Fatal error: Uncaught Error: Class ‘td_css_compiler’ not found in /wp-content/plugins/td-multi-purpose/td-multi-purpose.php:998
Stack trace:
#0 /wp-includes/class-wp-hook.php(324): td_api_multi_purpose::tdm_on_wp_head()

Can anyone help?

Thanks,
