Chas, if you find an older computer to use and need the editor, drivers, etc, I have it all backed up here somewhere and will dig it out.
I have it all and instructions posted somewhere in a thread here at Satguys, too. I'm on my phone right now, but whenever I'm on a computer again, I'll try to remember and find the thread. There's a couple of different drivers, a Xp one and a Vista one, IIRC.
If you get totally stuck and can't get access to a pre-Win 10 computer, I'll get it out of the boot-loop for you for free.
Course, you'd have to send it to me. Wouldn't need the remote, power pack, cable, etc, I have all that here.
