I found out only today my email i had been using suddenly shut down. I have been playing swtor for over a decade now, I cant sign in at all because for some reason it doesn't recognize my computer after playing on it the past few years. Please I need help fixing this. To change my email I need to sign in to the account but to sign in to the account I need to access my email. Please help 🙏.
