World Crash with version 0.16 with ios 9.3

After updating to version 0.16 on ipad 2. Worlds will not load for more than a few seconds before crashing. I've tried to redownload the app and paste the worlds in again. My worlds are working perfectly on my PC. I need to use my Ipad as a server with my students to morrow. They will be very disapointwd if they can't work in our world we built together.

Please HELP!
