I do not understand exactly what does it mean: “The settings page was there but the are no links in the admin”. What kind of links do you think?
On the product settings page there is not any links, just 3 checkboxes and 2 input fields, like on this screenshot:
Do you have this settings page, that is available in Settings / Woocommerce Custom Tabs menu?
You have one more menu: Product Tabs, that is on this screenshot: http://webshoplogic.com/wp-content/uploads/2013/12/WooCommerce_Custom_Tabs_Pro_Multiple_custom_tab_types_admin_list.png
Do you see this menu, and this page?
It may help us, if you send us a screenshot about the problem.
Thanks in advance.
