What this means is that your Internet provider has not yet received the updated "pointing" information that tells it where to direct you when you click on the link. Most ISPs update their information within 24 hours, but some smaller ones may actually take a few days. But to make sure your web cache is not also contributing to this, try going into your Internet options and choosing the option to delete your browser cache, and then visiting the link again.
Firefox: Click Tools, Clear Private Data, and then uncheck all boxes except cache, then click Clear Private Data Now.
IE 7: Click Tools, Click Delete Browser History, Choose Delete Files button from Temporary Internet File.
Then try clicking the link again. If it still doesn't work, please try again in a few hours.
