I too have been using Helix Native on Windows 10 for about 6 months with no problems and had updated to v1.92 withing the last few weeks. Yesterday, when I started up Studio One v5 and added Helix Native I got that same error. When I went to look at my devices on Line 6 site, they had me listed with one machine as duplicate authorizations and the other machine showed as Windows 8 and Windows 10. I have never had a Windows 8 machine. I suspect that Line 6 has some issue with their system and I created a support ticket and am waiting to hear from them in the next day or two. I was able to de-activate the incorrect machines but I do have to wonder what caused the problem in the first place. I also saw the new update for v1.93 and downloaded and installed it after fixing the device activation issue. The problem I have is that it seems to have wiped out my user banks so I had to import from my backups. Just thought I'd post my two cents.
