I've deleted temp files and made sure may browser is set up to refresh every time to the site. I'm still getting the same thing. I will try again tomorrow. I used your link also.
If you are on Windows you can open a prompt(command line window) and type in:
ipconfig /flushdns
And see if that helps. You might have to do a /registerdns too.
I've only had to do the above maybe twice ever so if it nukes your computer I'll apologize now. Hopefully someone more computer savvy than I can double check me or give better advice.
