iPhoto on iPhone 5s stuck on "The photo library on this device is being upgraded."
So I have a new iPhone 5s and I got iPhoto and when I opened it, it said, "The photo library on this device is being upgraded" and it was just stuck on that, not allowing me to do anything. I thought maybe I had too many photos (I had 1,500) so i deleted all my unwanted photos and I now only have 600 photos. Is anyone else having this problem, or have they solved this problem, or know the solution? Please help, thank you.
iPhone 5s, iOS 7.0.4, iPhoto 2.0
