Iam trying to cgnage emails off a email address that has crashed. I can log in fine, but if I try to change my email - nothing happens - unless the sysrtem is sending an email to an addressv I can't reach.
Contact the Support here (I'd say "account access" category). If you've bought rubies at some point, they'll likely ask you to provide some details about that to prove that you're the account owner. If not, I don't know what they check.
