Works for me, too. If you're not working with a new hostname that isn't up yet, like Norm suggested, is it one that's been up and working before but has now stopped? Does your website work, or is that down as well?
Do you have any other ones that you can login to that were working before?
As far as support goes, they advertise that they try to reply within 24 hours, but it's usually much faster. Until it's past 24 hours, it's still within the advertised window though.
