Purchase code not working for WooCommerce Amazon Affiliates that was purchased

I need to clarify that the purchase code worked for installing the plugin, but when I went to the developer’s support page to ask a question, it returns an invalid code response. It’s hard to get support for the app, when it won’t acknowledge my purchase. In their description, it states that we can have our own woocommerce products, as well as Amazon products on our site. However, it seems to override my cart and tries to take everything to Amazon. Other settings will allow my cart to work, but has me personally selling the Amazon products. I haven’t been able to find a setting that will make this work for both products. If anyone knows the solution, I’d be thankful. Otherwise, I’m hoping someone from codecanyon will chime in so I can get support there.

Did you purchase the item directly from CodeCanyon or Elements?
