Dear Alan,
I have enabled the shopping cart module on the page you mentioned in your email.
Please make sure you enable the cart on each menu item / page where you need it to work.
Basically module should be visible on each page you have "Add To Cart".
Let me know if more help is needed, and accept my apologies if I have delayed the support in any way. I really thought this is sorted out.
If I can do anything else for you, let me know.
Kindest regards,
Deian
