WP keep on redirecting to login page

i have 2 problems…

1. i’m using godaddy to register my domain: lunjai.com if I use forward with masking option to forward my domain, then my blog will become all broker, no theme, no images shown, i have to use forward only in order to have the blog works properly… any solution? i just want to have the URL show as lunjai.com instead of lunjai.dyndns.org

2. I’ve been having problem with login function, the wp log in page keep on redirecting me back to log in page continuously. I have try to reset the password at the phpMyAdmin and it still redirecting my back to login page every time. anyone can help?

Thanks.
