Hi,
This is my first attempt here. previously i wrote to pay@freemius.com but it didn't help at all.
1) I'm the admin of www.canalanimal.fr. So my email is admin@canalanimal.fr but there is no order recorded on this account.
2) Here are the events story. First, i tried the buttonizer free version, then i bought the premium one. All was ok. One day, i've deleted the free version from WP, and disabled the premium version. And when i've reactivated it, it asked me the activation number, that i don't have any trace, on any mail.
3) Here is the bank proof of my order : https://www.loom.com/share/cb287e6135784c4694785836bbecb02d
Thanks for you support.
