Try clearing your browser cookies, or at least delete any cookies for "e-junkie.com", and make sure your browser's cookie settings allow cookies to be set and kept until the cookie's expiration date -- if your browser is set to keep cookies only until you close the browser, then closing your browser window(s) would delete the cookie we set to keep you logged in.
Also bear in mind that you can only stay logged in for up to a week (i.e., even if you check "Keep me logged in", you would still need to actually log in at least once a week), and only from the same connection IP address. If your ISP assigns you a new IP with every connection session, or if you move around to different locations with different Internet uplink connections (e.g., work, cafe, home, etc.), you'd need to re-login every time your connection IP changes. That latter requirement prevents crooks from accessing your account if they steal your computer.
