If it's any help, there are at least 2 people who can confirm the DNS for your site is correctly configured (d3iti and I), so don't make any NS changes.
The dnsflush tool doesn't change NS, so you're clock won't start ticking again, it's just helpful for clearing local dns caches.
Finally!!!! If you absolutely are so keen to get started that you cannot wait any longer and it's still not working when you read this, you can use a free proxy and that should get around it until your dns is refreshed. Search for free proxy on google and you should find one.
