Hey I'm pretty new to minecraft and when I try start up a new world the game just crashes when it says 'Building Terrain'. Now I have tried a few things to try get past this but as of yet I have had no luck, so was wondering if your guys n gals had any knowledge of this and a way to conquer it.

Thanks in advance.

Here Is the crash report:
