Addshoppers in Bigcomerce store

Hello! We will soon start an ecommerce store on Bigcommerce. The site is good under way, but we want to add the extra feautures of addshoppers to boost social media. But we have problems to integrate the addshoppers app into the store. It doesnt work properly. So if someone out there can help us out, we would be grateful. Hope to hear from you! John
