Login Error

So I tried logging on to my account after I had finished college today and when i tried, it came up with the following message:
"Cannot launch FINAL FANTASY XIV: A REALM REBORN. Please register the promotion code included with your package or download. A re-install will not be necessary."

When I press the X button to continue on, it comes up with the following message:
"A system error has occurred: -2147309046"

It's been doing this for over an hour. I'm getting more and more frustrated because I've never had this problem and I've been playing since it was released to the public. I'm not sure if it's due to the maintenance that PSN is doing at the moment.

Could someone please clarify this for me and/or help me with this problem? I would really appreciate your comments.
