insanctus,
Doing a traceroute, your domain is still going to your old host. It must be for you too with that it is trying to connect to Blue Lagoon there, which it can not as it is not your selected theme on that server. Once DNS probagates to our server it should work fine. until then, you could try using the ip address we assigned you instead of
www.domain.com
Also, I hope you find our service reliable with faster support .... Welcome aboard
