For anyone attempting to test this out, you also need to run the following query to the database:
Code:
UPDATE `altadv_vars` SET `hotkey_sid`='5662', `hotkey_sid2`='5663' WHERE `skill_id`='643'
(Or just manually set hotkey_sid and hotkey_sid2 to 5662/5663 respectively for the Project Illusion row in the altadv_vars table)
(thanks AndMetal for the string values)
