Cross DJ Free v 1.8 iOS won't load library

I started with the free version and bought the in-app option to unlock everything. I enjoy the app very much but now It no longer connects to my library. After it did the update to v. 1.8 on the title screen I got a message saying "loading Library". After it got to 100% complete and the app launched I was unable to select any music on my phone in Cross DJ. Also all of my previously unlocked FXs etc are all now locked again. I've tried deleting and reinstalling through the App Store and I get the same result. Nothing from my library will load. Any help would be greatly appreciated.
