If you pre ordered FF7R on the Square Enix Store you'll need to check your email. After the delay SE issued new emails to those who pre ordered directly from the SE Store. Even though if yours is paid off you should still receive this email like I did. Basically they're just letting you know that the release date has changed and that you must opt-in to keep your pre order in place. SO MAKE SURE YOU CLICK THAT RED BUTTON!!!
Once you click on it, it takes you to the Square Enix Store where it confirms you opted back in.
That's it, all done.
