Schema.org input missing?

I’m not getting the schema.org like rating that you can see on your image here: https://aihrus.zendesk.com/attachments/token/xqabxzugrjoqs8k/?name=Better+Testimonial+entry.png

Ratings come in the premium version. Buy via https://aihr.us/products/testimonials-widget-premium-wordpress-plugin/.

Bought the premium version, deactivated the free one, installed the premium version (upload via ftp) activated getting the following error:

Warning: require_once(/home/huidtherap/domains/huidtherapievechtstreek.nl/public_html/wordpress/wp-content/plugins/testimonials-widget-premium//../testimonials-widget/lib/class-testimonials-widget-settings.php) [function.require-once]: failed to open stream: No such file or directory in /home/huidtherap/domains/huidtherapievechtstreek.nl/public_html/wordpress/wp-content/plugins/testimonials-widget-premium/testimonials-widget-premium.php on line 1803

What goes wrong here?
