I have purchased this extension and it works very well. Except I had a "Add to Cart" button on my category page that broke this extension. I had an overide in the category template that put the add to cart button under the product details button. It worked perfectly with all products EXCEPT the downloaded ones which it didn't put a link in the email.
I really want an add to cart button on the category page. I have used various solutions through the forums, but still none work. Can anyone help?
