Application Error Configurator Specified cast is not valid

Getting this error when trying to open the Configuration of part from Quote Entry. I have removed personalization from my account and this seems to work just fine on another users computer. I have deleted the Program Data files and still getting it. I have removed the control that it references but still getting that message.
