"Impossible to link a non-certified ankama account"

I just got wakfu on steam yesterday, and I logged onto the launcher completely fine. I had to pause the download and exit before it could finish, and now when I try to login through the launcher it says "Impossible to link a non-certified ankama account"

I don't really know what it means, since I already verified my account through email and already logged into the launcher once before, so what went wrong?
