In internet wording, a cookie is just a small piece of information that is saved to a special storage space on your computer. A cookie generally only contains an ID number that is unique to you. That ID number corresponds to information in a database, and this kind of matching of IDs between cookies and databases enables many of the things that make the internet work. Cookies cannot be used to run programs or deliver viruses to your computer. Cookies are uniquely assigned to you and can only be read by the same website that gave you the cookie.
It's very important that cookies are enabled in your web browser for access to our sites. There are two types of cookies: first-party cookies and third-party cookies. To access our service, make sure you allow third-party cookies.
To enable cookies in Internet Explorer, go to the top of browser and select Tools, then scroll down to Internet Options to select it. This will open the Internet Options box. At the top, you will see tabs labeled General, Security, Privacy etc. Click on the Privacy tab, and you should see a slidebar that moves up or down. Grab it and move it down to Accept All Cookies, then click Apply and OK to close the box. This is the typical cause of most log in problems.
As for firewalls:
Many members wisely choose to use internet security software such as Norton Internet Security, McAfee Internet Security, or Zone Alarm Pro. This software includes important anti-virus and firewall functions. However there are also features in this type of software that are designed to protect your privacy by blocking cookies and hiding your internet activities from the web sites you visit.
We are not suggesting that you turn off your security software, in a manner of keeping it turned off. As stated above, anti-virus and firewall software is very important. What we suggest you do is change your software's ad-blocking or privacy settings so that tracking cookies and links are allowed, thereby allowing access to log in. In extreme circumstances, disabling or turning off the firewall may be the only solution if unable to adjust the settings. But rest assured, once logged in, you can turn the firewall back on.
Besides your web browser and internet security software, there could be other parts of your computer or network that are blocking cookies and preventing you from earning reward points. Because there are so many different software packages, computer systems, network environments, and ISPs, we are unable to provide specific instructions for all possibilities.
