Forgive me for my lack of finesses of the English language, but is "Me" referring to "You", the capita letter only being for emphasizing it's you and no one else suffering from this issue?
If that's what you're talking about, you might have issues with the name server. At first I was thinking about the two arenas being on different servers, but it appears they are on the same one. Nevertheless, it doesn't hurt to flush your DNS cache: Open an administrative level command prompt and type "ipconfig /flushdns" without the quotes.
Another useful trick is to power cycle your modem/router by simply unplugging it from the mains for some 30 seconds. Replug and wait for the connection to come up again, see if that helped.
