Hey Fábio,
Thanks for reaching out to us!
I apologize for the inconveniences you experienced when trying to purchase our plugin. I’ll reach out to our team for help in reviewing this on our site. As a test though, would you mind retrying today to see if this was a temporary issue?
In the meantime, please send an email to support[at]theeventscalendar.com with a link to this thread. We can get you copies of the plugins you’re wanting. Then, once the payment situation is sorted out you’ll be able to get a full account with access to updates and support.
Let me know if this helps.
Thanks!
