--- Comment #6 from Vincent Povirk madewokherd@gmail.com --- I think it's expecting c:\users<username>\Application Data\Gruss Software\Betting Assistant\user.config to be created automatically by the framework somehow. If you have a working user.config file, you might be able to work around the exception by copying it in place.
