Have you recently changed your main domain?
I see you only signed up today. There could be a 48 hour or more waiting period before domain changes "propagate" across the internet, meaning you'll see the default web page cgi until it has finished. The only thing we can do is say keep checking, and clear your cache and flush your DNS at regular intervals.
If you're still having issues in 48 hours, please post back and someone will investigate further.
