Just installed Beta 3.1.5.5 Rig Manager
No communication with Profiler Head. Nothing at all.
(Restarted RM, Profiler, Changed USB lead, Changed Port: No improvement)
Uninstalled and reverted to 3.0.145
All back to normal after a Sync (same lead, USB hub port, etc that I always use)
Profiler is running 8.0.6.24597 (which seems to be most current SW version)
Computer Gigabyte Aero i9, Windows 10Pro
Just thought I'd report this, in case anyone else is having the same issue
