Custom user registration message

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.3.3
-- PHP version -- : 5.4.7
-- Error-message(debug-mod must be tuned on) -- : Custom user register message

I am using Hikashop User registration form. After user registers i get message prntscr.com/5zv20c .
I wanted to customise this message. Tried making changes in language/en-GB/en-Gb.com_users file , but could't find the line which i can there. Where i can customize this message.

Hi,

You can modify any text of HikaShop with a translation override:
hikashop.com/download/languages.html#modify

The text is defined in the language file "en-GB.com_hikashop.ini".

You can change it per language override of the namekey HIKA_REG_COMPLETE_ACTIVATE, either in the usual Joomla way, or following instructions here: hikashop.com/download/languages.html#modify

Beware of modifying the original file, as you'd lose modifications when updating.
