First, since this hasn't been mentioned I would suggest you do a Windows update, but do a "Custom" instead of "Express", so you get all of the updates and not just the critical ones. Could be one effecting the way the path is listed.
You may need to do a clean install of Hoster. That would be to uninstall, then do a search of the registry to delete any "Hoster" entries, and last delete the Hoster folders in the Program Files area (do not delete your kma storage folder or you lose all you imports). Reboot and then reinstall. Your registration information will still be there as that file is outside of those folders.
