I am also having the problem mentioned here:
http://www.gravityhelp.com/forums/topic/woocommerce-add-to-cart-not-working-when-using-gravity-forms
but you refused to help in that thread and instead direct us to Woocommerce, but their forums are only open to customers, and we bought this pluggin from YOU!
It's your product we PAID you for so will you refuse to even try to help us?
