First, check for the obvious:

1. Are you using a "private" window or session? Private sessions will delete your cookies after you finish using the website—including the code to log you in automatically.
2. Is another member of your family or a visiting friend logging you out then logging into their own account?
3. Are your browser preferences set to automatically delete all cookies upon closing the browser?
4. Do you have cookies turned on?
5. Some anti-virus software may delete cookies from your browser to prevent "tracking" or to hide websites that you have visited. What is else is your anti-virus software doing besides checking for viruses?

If one of those is not the problem, then a "cookie" in your browser has probably become corrupted. This most often seems to happen when someone imports data from one browser into another, such as from Internet Explorer into Firefox, but regardless of the reason, you'll need to delete the cookie.

If you're using Internet Explorer

1. Click the Tools option.
2. Click the Internet Options option.
3. On the General tab, under Browsing history, click Delete.

Note: This will delete all of your cookies in Internet Explorer and you may have to log into other websites again as well as Atlas Quest.

If you're using Firefox

1. Click the Tools option.
2. Click the Options... option.
3. On the Privacy tab, click the Show cookies... button.
4. Click on the cookie for site atlasquest.com with the name cAutoLogin6.
5. Click on the Remove cookie button.
