Excellent thats done it, I just used mysql commands from the terminal, I'll paste it below just incase anyone else happened to install during this period!!
mysql -h localhost -D itflow -u itflow -p
(will ask for password, which was given to you after running the install script and hopefully recorded!)
ALTER TABLE `user_settings` ADD `user_config_remember_me_token` VARCHAR(255) NULL DEFAULT NULL AFTER `user_role`;
