Hey gang! Glad to hear you're getting your shipment confirmations now!
I wanted to include a link to our Support Center that details how to redeem your Spinet in-game reward item for those of you unfamiliar with the new procedure (since moving over to the Square Enix Account Management System). Here's the link: http://sqex.to/UcS

And here are the steps for easy reference!
How to Register the Spinet
Please follow the steps below to redeem the reward code and receive the item:
  1. Log in to the Square Enix Account Management System, select "Select Services" from the side menu, select "FINAL FANTASY XI," and then select the "Add a service account" button.
  2. Follow the onscreen instructions to enter the reward code and select which FINAL FANTASY XI character will retrieve the item.
  3. After registration, log in to FINAL FANTASY XI with the character you selected and go to any of the three starting nations to retrieve the item from a Festive Moogle.
  • The Festive Moogles will be placed near Mog Houses in the following areas:
    Port San d’Oria (J-9), Windurst Walls (C-14), Port Bastok (J-13)
  • You can retrieve the item from a Festive Moogle in any area.

Notice
  • Please ensure you have registered a FINAL FANTASY XI content ID and created a character before registering the reward code.
  • This campaign is limited to one reward code per character. Even if a different code is used, that character will not be able to accept more than one item.
  • Reward codes cannot be re-used, or re-issued to another character.
  • Codes cannot be exchanged, refunded or re-issued.
  • This item is Rare/Ex meaning that it cannot be given to other characters, sold at an auction house, or sent using the delivery service.
