I have the ultimate collection for xbox. Bought it about a month ago. Took me about 2 hours to figure out how to get the reg. cod to work. Go into the expansions section & register one of the add-ons with the code. It will then prompt you that this is a one time reg. code. You can then click the other 2 expansions & they will all register. No problems at all man. My game library only says FFXI not "FFXI Ultimate" also.
