Hello nelsonmcunha,

Thank you for getting in touch with us. My name is Attila and I'm happy to assist you today. I appreciate your patience while we've been working towards your ticket.

Unfortunately we cannot swap the two items as Envato does not provide such option for authors, but we can offer a refund. Please proceed to purchase the WordPress version, and open a refund request on the official Envato channel for the mistaken purchase so we can accept it.
