If you input the correct username and password for your acount and cannot login (even when it showed a "green Check mark") then:
1) First check the information sent to your e-mail during your registration to see if your inputted info was correct.
2) check if your firewall or anti-spam if it is blocking any information on our site. Don't worry, CoKoRoX is virus/ad-aware free so you can unblock our site.
3) You can also clear your internet cache and history...
4) Or simply download Mozilla Firefox, which is what I use to edit the site mostly, plus FF is a lot better than IE.
