The Kemper is on 126.96.36.19941B and Rig Manager is the latest Release V 188.8.131.5251.
I have no communication between Rig Manager and the Kemper - at all. Multiple restarts etc. did not help.
I'm on Windows 10 64-Bit, 1803, all drivers up to date etc.
But Rig Manager does not find the Profiler.
