Better off to use Kaspersky Rescue 10 (A FREE..pre windows boot, file browsing tool) download and burn the iso to a cd, turn off your internet put or leave the cd in your optical drive and reboot, ignore the request for anti-virus update,open the file manager, find the .mis file(s) and save to a location you can get to in windows. Nothing can hide or ignore commands from this program.
Back-up your entire BHD folder and archive the back-up, noting the the original install location just in case "do not uninstall it!".
Then reinstall BHD using the installer default settings and you know what to do from there
