This is not a theme issue per see but I can not see any other place to post this.
I have purchased two themes and I want to upgrade my license to club.
They sent me a coupon code but for the life of me I cannot proceed to the checkout page. When I click on it it just takes me back to the login screen and in a round about.
Even if I try to purchase a theme the same thing happens.
I've exchanged emails, about 5 so far but still no help/solution from AppThemes.
PS: When I hover over the (Proceed To Checkout) link I get a url sending me to /signup.php
