I can't seem to recreate this error. My saving and loading have been fine. Perhaps you have files from an older version of the game? If so, navigate to C:\Users\(Username)\AppData\Local\Gyakuten_Live_ and delete or remove the problematic files.
I'll make a post to my Twitter to see if anyone else is having the issue. Is it happening every single time you try to load a file or is it only happening after a certain series of inputs?
