Well as far as I know, accounts will never expire unless you stopped playing right after Beta. Even then, I doubt they'd let it expire. Contact CCP account people, let them know your account was hacked, because that's what it sounds like, and then go through the steps. Or tell them what the hell and sort it out like that.
As for the ETC, it should be part of your account reactivation thing and has a simple 'how to enter' set up.
