I've got unexpected problem with kat-osx. Trying to press on "Focus training" led to program's collapse and corruption of the database. After repeted attempt to do this (silly me) I simply can't open the program again due to 'Error: The database could not be opened....'.
I don't want to restart the box right now due to many processes running, but what're my options? Should I re-install? Kat was happily running from mid summer last year, lately unused most of the time, starting it once in awhile to see if any progress was made.
