When cookies refuse to cook, it's the oven's fault. Er, I mean the browser's fault.
The "Delete All Cookies" option at pipTalk relies on your favorite browser following our orders, and too often, it doesn't. It happened to me just yesterday, at a different site, where my cookie simply refused to change no matter how many times I reset the site option.
The solution? You have to manually clear your cookies directly in your browser.
IE 6 From the menu, Tools, then Internet Options. Click on the General tab if necessary, then "Delete Cookies."
FF 1.5 From the menu, Tools, then Options. Click on the Privacy tab if necessary, then "Clear Cookies Now."
