I get this error when I'm trying to access to my account: I've already reported this issue via their official @aolmailhelp twitter channel but I haven't got any answer yet.
AOL is shooting itself in the foot. I've had an ongoing issue with them. Sometimes they deliver the activation emails when our users open accounts or post ads, sometimes they don't. I figure it's better not to use AOL as an email provider and go with either yahoo or gmail instead.
