Responsive Tabs with WooCommerce Product Tabs Extension Tutorials

i need this plugin for free

I just updated this plugin to version 3.7.3; the prior version works and this latest version is broken - a total showstopper. I have to back pedal to the prior version by replacing the staging WP environment with a new one from production. Then gradually transition to a different tab plugin for the pages that are using it unless there is a quick resolution. Is there anything I may be missing that will fix it?

how can i export my tab design as i couldnt find the export option anywhere
