I've contacted EA Portuguese support, who referred me to the chat so that my problem is solved. My call is open with number<edit for security reasons >, for the World Dragon Valley. The attendant said that here the support could check my data and give me a new code for the game to work properly.
I await feedback as soon as possible.
