On second thought, I know I fired up Axe-Edit... And I didn't get any pop-OR- errors, but I also don't think I used it at all.
Did you get a pop-up error box or not? If not, possible I missed it.
Got a pop up from Axe-Edit and refusal to work. Its a hard stop.
Still poking. My Surface decided it needed a Firmware update, then a bushel of Win10 updates. I'll let those finish and I'll try stripping out all signs of Axe USB bits then re-run the FAS USB installer.
