Sysex Transfer Pc->korg M1, MIDI MATE cable Options

[Seersholm]

Hi guys

I've tried everything:

I just can't get the factory settings and sounds back into my Korg M1. This is what i've done so far:

I bought a socalled MIDI MATE cable which connects my laptop with the keyboard (USB-MIDI)
I downloaded the m1preld.syx file from the internet.
I d/l'ed several transfer programs.
Cable is connected with MIDI out to MIDI in - and visa versa.
I set the Global MIDI channel to 1 on the keyboard
I used the programs one by one to send the file, but the keyboard do not respond with the right sounds.
I am able to transfer *.m1p files, keyboard shows the sound names, but there's no sound out of the keyboard.

What happens:
Mostly nothing.
After some tries with the sysex transfer, the keyboard shows some sound names with absolutely no meaning, and theres no sound out of the keyboard whatsoever.

Anything that might help is GREATLY appreciated.

Thanks
