[Resolvido] Website lost connection to WPML servers and lost its key

Background of the issue:
I am trying to use WPML without finding new bugs. About a week ago, I migrated a site from devildivers.pro to angeldiver.pro. WPML noticed the change, and I chose the option that I migrated the site, making angeldiver.pro the only site in use. It seemed to work, and I think it also migrated the translation memory. Link to a page where the issue can be seen: link oculto

Symptoms:
Today, angeldiver.pro told me that the connection expired, and I need to refresh the account. It wants me to provide a new site key. On my WPML account, I can see angeldiver.pro as a site, but there is no site key for it anymore. This site and at least one more got disconnected at the time of my subscription renewal. The other site reconnected because it already had a key, but this one is missing the key.

Questions:
Why did the site lose its connection and key during subscription renewal?
Is my translation memory still intact?
How do I re-connect it, so everything works and without loosing translation memory?
