Unable to load save

I played for a while this morning, and saved right after meeting Bellara.  When I came back several hours later, I kept getting an error message that just said 'Unable to complete request' while loading my save.  I would get all the way through the loading screen to the point where you could see my character and my party, and then I would get that message and have to quit.  It happened with both my manual save, and the autosave 11 seconds before that.  I had to go all the way back to the beginning of the chapter save to be able to actually play.

This is one of multiple problems I've had.
