I tried to sign in my account as usual with a different PC (old PC stopped working for some reason before i bought new one). it asked me a verification code to be able to log in. But i lost my email address long time ago. So i submitted a ticket to Lineage 2 Support Team. They asked me all possible emails etc.. I told them correct email address, date of birth, location, credit card and paypal. But what they replied to me was that " we strictly need you to contact us using it or the email currently linked to it. Unless you are able to, I'm afraid we won't be able to provide any assistance ."
