I have been having the same problem for about a week. Got around it by trying Skrill - that worked once and is now not working either. Still waiting for my support ticket to be answered although it is within the 2 - 4 day waiting period Envato mentioned in their news area.
I disagree that this isn’t the place to post this kind of thing. It is the exact place to post this kind of thing, in fact. That way it becomes known as to whether or not others are having the same issue. But that is just my opinion.
