Hi Lucin
I have some questions about details we need
-have you ever performed a system update before, using the same card and adapter?
-did you copy the files to the card root directory (not in a folder)?
-yes, provide the tests results, please.
The fact the LED is off is caused by the upgrade procedure not running. That's normal. If you want to check the LED you can remove the card and try with any MIDI message signal.
You can exit the tests by powering the unit off.
You can reinstall the OS…and your presets/setups if you have a backup of them.
all the best
I
