Never have I ever kept a world in Minecraft. So as I was creating a new world today, I put it on creative and turned off cheats and the other thingy that stops villages, dungeons, etc.
When I clicked "Create World" it went onto the loading screen, and just stopped on Converting World. I have been angrily attempting to resolve this issue for the past 40 minutes, and I'm getting extremely frustrated. It won't close, either. So I have shut down, logged on and off, and jumped on my computer about 4 times. Each.
Please help me before I punch a hole into my computer screen irritation.
