I tried logging in too after being away for some time. Old email is not active anymore. Some security feature forces me to click a link sent to the old email. Tried with changing email address. Worked almost. Got a link sent to the new email but when clicking it I am forced to click yet another link sent to my old inactive email. Catch 22 situation. Think it through next time you implement a system that forces users to do something so that it is actually USEFUL.
It's user's responsibility to keep their contact info up-to-date. 1) send a ticket to eu.4gamesupport.com to change your email to the one you have access to 2) Trusted PC is not an obligatory feature, just a good way to secure access to your account, so no "forcing" here. Confused with Classic, my bad, it's obligatory, but just 1-time.
