In my support tickets I've been using a yahoo address.
I can't think of any way to get my domain email address working.
I guess its a good lesson for me, not to put down my domain address in the whois entry.
Looks like the whole account is shutdown.
webmail.kjdomain.com works, but I can't get log in.
I can see my old support messages in the support history, but everything else is missing - domains, registrations, users, groups, etc.
I can't see anything obvious to indicate a problem with the billing.
