Hello, 

I've had mincraft for a very long time. This is the second time it will not load my world. I don't know what else to do. Everytime I try to load my world. It just keeps saying "there was a problem loading this world.. now I am really worried that my world will never work. I've tried literally everything, restarted my WiFi, deleted the game and reinstalled, deleted the world and redownloaded it through cloud saved data as it worked last time but this time it just doesn't want to work at all, I've restore licenses, I've checked for updates, I've pretty much done it all. My heart is coming out my chest, my world is massive! I've done so much I don't want it to be gone forever. Please help me!
