Problems with Profiler - Rig Manager

    I seem to have run into a problem I can't solve. I have updated my Kemper Amp to OS 5.1. (beta) as the RM 2.0 advised me to. Still RM doesn't seem to identify the profiler any more. "profiler (0)" is blinking a couple of times before it disappears. Going back to RM 1.6. did not help, it made my whole system crash with a bluescreen. I have uninstalled the RM every time before re-installing it, but it did not help. In a previous attempt with OS 5.03 on the profiler, RM started counting the profiles but stopped at 23 or so. I turned off and re-started the profiler and the whole problem started. Any combination since then does not work together, including the update to OS 5.1.0(Beta). Any ideas guys?
