It really takes a lot of time and energy!
I am not sure if this was really a bug or not , but editing addresses dont work in address_book_process.php to change or add a new address , so I take a deep look at the whole files , Finally I found out that in /includes/ajax.js.php function getStates refers to create_account.php and this function also used in /includes/modules/address_book_details which completes the page address_book_process.
so if you need this module to be worked another functions ,seperatly for address_book_process should be added to summerise:
in /includes/modules/address_book_details
'onChange="getStates(this.value,'states');"'
to :
'onChange="getStatesAddressBookProcess(this.value, 'states');"'
and use the new ajax.js.php which I uploaded
