just read in a post, some people are having problems changing there login password, i know i was for ages and then stumbled upon this, instead of selecting USER CP - EDIT PROFILE - EDIT EMAIL & PASSWORD, if you look in the left hand margin at the bottom under USER MENU there is A MY PROFILE option, this will bring up a sort of contact card of your profile including avatar, last online etc, click on EDIT and then select UPDATE YOUR PROFILE this will present you with two tabs 1. Additional info and 2. contact info, select CONTACT INFO and here you can change your email address and password, don't foget to click on UPDATE before closing the window, this worked for me so hopefully will for others.
