Put the summary of the bug you're having here

What I expected to happen was...:
When I click play, I expect the game to load.

What actually happened was...:
No matter what world I try to open, when I hit play it starts to load and then a white screen shows "fatal error." I haven't been able to play a game for months.

Steps to Reproduce:
1. Select single/multiplayer game.
2. Join a server and hit play.
3. It will say "loading terrain" and then once it loads, the screen will turn white with a large description of the fatal error. A copy of the error is pasted below:
