Updated profile doesn't work

I requested a new password when my old one wouldn't work. i later found out that the site was having a little hiccup. i requested a new one and was given a long alpha-numeric password. now I updated my profile with my old password and when I log out the password I created doesn't work. why?

Err, you entered it in wrong? Had caps-lock on? If you change your password through your forum profile then it will work just fine.
