''Could not load track'' with the latest iOS version on Ipad

Hi, so here is my problem. I just recorded a 5 hours long mix for one of my friend. I then tried to load it in the app to listen to it quickly. The app gave me a ‘’ Could not load track. Please update your device to the latest iOS version to support this file type’’ (Which I did). I also tried to open it on Itunes, still doesn’t work. What’s the problem ??

I am using DJAY 2 on my IPad with the newest update.


Does that only happen to your 5 hours Recording or to any Recording you made?
