For paypal users:
They answered me on the email, telling me that the problem was because my paypal was requiring me to refresh my account information. And that is why my payment was delayed. But, I did open the paypal several times, and it only required me to refresh the information on day 13 of this month(I remember well because I did receive another payment from other sources this day).
So don't know, maybe double check your paypal to see if there is something there.
Still, it took two weeks for them to reply to my e-mail with that information =/
