Impulse is the only place to obtain the latest updates. You might try uninstalling the game as it is now, reboot your PC, then re-install just using Impulse. It should install to the latest version.
About the Mini-dump files, you mentioned that you got a 'dump' file, I assumed this is the 'mini-dump' file error. When the error occurs a popup lets you know and you can access that mini-dump file, which you then e-mail to support@ironcladgames.com for help.
