Well, I cannot see your WooCommerce System Status… as you did not supply that when creating the topic. How about you share that with me, so I can see what is going on.. wp admin > woocommerce > system status.
You need these three plugins, in this order:
1. WooCommerce installed & configured
2. WC Vendors 1.9.8 installed & configured
3. WC Vendors Pro 1.3.9 installed and configured.
