I like the beta program - seeing new stuff a bit earlier. very cool.
This is the first issue I've had.
I updated to the 8.7.4.37194 Public Beta. Rig manager (latest version) now pops up the "your usb connection is unstable" message.
RM can see the profiler - but doesn't show any profiles on it.
Its never popped this up before. I've tried a different usb cable, and moving the usb cable to a different usb port on my pc.
I'm going to try rolling back to the 8.7.3.36999 Release, then reinstalling RM.
I'll let you know how I get on.
