I open my character animation project to do some work. And lo and behold, what do I get?

UNRECOGNIZED FILE TYPE :DDDDDDD

And do I have an ASCII version of it? OF COURSE NOT! Which means I get to redo hours' worth of animation! OH JOY AND RAPTURE AND SUNSHINE AND PONIES.

So much for getting home at a decent hour tonight.
