Issue: Doing firmware update on Windows 8/10 causes the AT-HD-M2C to stop working and the power light no longer lights up
The AT-HD-M2C can be updated using Win XP, Vista and Win7. Windows 8 and Windows 10 treat the firmware file differently which can cause issues with firmware updates.
If you would like to reinstall the firmware, please make sure you use a Windows 7 PC. If you need to use a MAC, please use VM Fusion with Windows or Bootcamp (running Win 7 or ealier).
