I got the following messages for several days and cannot get access to the page. Address Not Found Firefox can't find the server at www.clickbank.com. The browser could not find the host server for the provided address. * Did you make a mistake when typing the domain? (e.g. "ww.mozilla.org" instead of "www.mozilla.org") * Are you certain this domain address exists? Its registration may have expired. * Are you unable to browse other sites? Check your network connection and DNS server settings. * Is your computer or network protected by a firewall or proxy? Incorrect settings can interfere with Web browsing. At first, I thought there would be some problems at ClickBank, but when posting my question at DP, they told me it's working properly. So, maybe there's a problem with my laptop or antivirus, etc. One guy suggested me to post my question here. Can anyone suggest how I should do to solve this problem? I'm using WIndows Vista Home Premium with Bit Defender 2009.
