Woo Variations Style Buttons (WooCommerce 3+) Not showing images

Hello,
 
This is an update ticket from previous email sent you from agata@barcelonaconcept.com on 09/05/2018.
 
I have purchased woo variations style in order to get last version comaptible with woocommerce 3 but also to get active license.
From my plugn backend says that license is active.
Now, with new plugin version, I am having same problems than before upgrade:
Image attributes doesn’t appear. Plugin loads a white box on add-to-cart zone but nothing else.
I tried to add images manually and all possible combinations but nothing changes.
Please, check a product to see the issue:

From archive.org, you can check previous images:

Please, what is supposed I have to do to get it work again. I am scared just to think that I have to add manually all variations again.
Thank you for your attention.
Best,
 
Albert
