Are we looking the same place?
When I go to the Mog Station, I get a first row of buttons saying:

Account Services | Optional Services | Service History | SE Account Settings | Support Center

(Then below it it shows my service account. Text indicating to select the account suggests this could be a list of service accounts for people with more than one.)

If I click on the first "Account Services" button, it brings up another row of buttons below it, within the listing of my service account. That row has:

Subscription Services | Enter Bonus Code | Upgrade to Digital Collectors Edition | Add Windows Service | Update Payment Method | Enter Pre-Order Bonus Code

Clicking the first "Subscription Services" button from that list brings up the "Select Subscription Type and Period" page.

How much of that are you seeing before it diverges from what I had?
