Due to a bug in the new version of another app that I use, I had to change my OS X user account name -- it had to do with a space in my original account name. I followed Apple's instructions for changing my account name, and all of my other apps (so far) have accommodated this change well.
Unfortunately, when I go to File, Open Brain, all I get is a list of my .brain files under the old, nonexistent account name. If I go to the .brain file in the directory, upon a click the focus shifts from Finder to PersonalBrain, but the file does not open. No error messages are generated.
Is there some way I can get my app to find it's files again?
