Error in trying to draw the scene

[DensetsuNoKaboom]

This morning Alice 2.2 was working fine.

Now every time I start it up it says "An error occurred in trying to draw the scene. Simply retrying might fix the problem." Simply retrying does not fix the problem, and if the problem's not fixed the world shows up as a black screen and I can't do anything.

A little help here?
