Versions earlier that 1.8 crash when a saved world is loaded.

Today, the first day of Dinnerbone's snapshot release of 15w31a, I tried loading up liteloader on minecraft version 1.710, to use world edit. I can get to the Menu page, but when trying to enter or load a saved world up, the game crashes and gives me this error code:
