Background:  I have been reading about how some people go into the nether and "get stuck."  Well, I wasn't doing that at all.  In fact, on my game, I was just chopping trees, buildings walls and decided to save/quit and now I cannot get back into the game.

My daughter started the world and I joined in.  I have been playing for about a month now and I really like Minecraft, but I have heard some horror stories online.  I am living it now.

My daughter will load the game, seems to come up fine.  Then I join in like I usually do but the split screen just gets stuck on "Building Terrain".  The loading bar is like 99% done.

The WEIRDEST thing is that my daughter can see my character on the land but I cannot do anything.  Even more weird, she tosses me items and my character clearly picks them up... but still nothing.

HELP!!!  I feel like everything I have been building is a complete waste now.

Picture:  On the left is my daughters screen where she can clearly see my character in the world, but the screen on the right is the "Generating World, Building terrain" screen.
