I preordered the game and used my pre-order registration code to get into the early access. But I bought the collector's edition and the system says I have the normal. I found on the FAQ how to upgrade to the collector's edition.

Follow the steps below to upgrade to the Collector's Edition:

(1) Log into FINAL FANTASY XIV: Mog Station

(2) Select "Subscription Services"→ "Upgrade to the Digital Collector's Edition"

(3) Follow the on-screen instructions to complete the process.

*Please note that you cannot use a Game Time Card to pay for the digital upgrade
The problem is that the Mog Station does not have a "Subscription Services" link anywhere I can find. The only place I can see to enter a code is the wrong format for the one I have.
