My Manhattan RC-1978 lost movies mux on SES-1 when coding changed. Several blind scans failed to restore them. Downloaded the latest software upgrade from Manhatan site (several years old) Put upgrade on SD card and plugged in to receiver. the programme (GX6622-MAN-08-0) partially loads then after 14 bars indicated shuts the the receiver off. Then after a few seconds it comes back on but programme not loaded . Have to go back and restart programme loading with same shutdown routine. I have redownloaded the upgrade from site and used a new sd card with same result. My cheap chinese receiver is able scan in with no problem. . Is there something wrong with my receiver or update sofware?
