J-BusinessDirectory - No Payment Button

Hi, I've just got my website customised and started putting businesses in but the payment button isn't displaying after they create their business. I'm not sure if I'm doing something wrong or if there is a problem with the site. I tried it in your demo version but mine doesn't seem to work the same way. Please help!

Its ok now, I changed it to the free basic one, then to standard which worked, I then put it back to the premium one and it worked.
