Custom Product Tabs PRO not showing in admin/products

Hi,

I have moved an opencart site to a new server and all works ok except the ' Custom Product Tabs PRO ' module. The module load ok but the extra tabs previously set up are missing. They are also missing from the products page. When I try and add extra tabs it allows me to add the tabs but only show one on the product page.

I am new to opencart so any help would be greatly appreciated.

Thanks
Graham
