Ok, so I left it 24 hours before I sent a support message. After 24 hours I thought it would have pleanty of time for the DNS to propergate.
The support message has now been in for 12 - 14 hours (i've lost track), and still no response, and still no web access to the MySQL DB. Worse still, I now can't even get into my web control panel.
What's going on DH?!?!!!!!
