If you can give me admin access to your site dashboard (email me at admin@togethernet.co.uk) I can give it a try for you, otherwise I would need to set up a testbed with Visual Composer installed and that might take me some time to sort.
I’d soon be able to tell if it would work, and if not I am happy to refund you. I am aware that the plug-in will not work with every theme on the market.

Ken
