Tele,

All of our releases for FINAL FANTASY XI since 2008 have included a universal registration code; a single code that provides access to whatever content the release includes. So the one registration code you were provided with that purchase will give you access (in the case of that release) to PlayOnline, FINAL FANTASY XI, all four expansions, and all add-ons.

For any further questions, however, please contact the SQUARE ENIX Support Center directly for assistance. This forum is for the discussion of technical issues only, and while this may seem like a technical issue, it is in fact something covered by our account & billing teams.

Unfortunately, since this situation does not involve any technical trouble, we have had to lock the thread.
