Thanks Jimi6. All this, Yes! But one more thing:
3.5 Turn off any Screen Saver / Sleep mode on your computer!
That step is mentioned in Line 6 Central, but not in the release notes OR HX EDIT. (at least that I saw...)
I spent a few hours chasing all this, but we are finally OK. On my first try getting 3.8, HX EDIT left my Helix bricked. It won't even say it exists.
Various helpful threads treated this problem before, but they sent me back to LINE 6 UPDATE, which is a bridge too far back. Finally I landed on LINE 6 CENTRAL. It finally could at least see my HELIX, though it still failed update several times. Until I carefully read the steps again, and turned off the Screen Saver / Sleep mode.
