I'm not sure if this is the right category, but I haven't been able to buy anything on the add-on store during the past hour. Another guildie tried it, too, and couldn't get it to work. I'm using Windows 10, and tried it in Edge, Firefox, Chrome and Opera. I can get to the payment page, but it doesn't continue past that. It only reloads the same page. So, using credits, nothing happens. When I tried using PayPal, it still only reloads the same page, without continuing on to open PayPal.
