Using latest Rig Manger for OSX, Kemper loaded latest Firmware release. Going through My Profiler rigs folder towards the bottom in Rig Manager and clicked on a Rig and got and got an error on the Kemper screen. Said to contact support, so here it is, hope it helps.... attached is a screenshot of the error. Interesting, I might be wrong but I didn't know that the Kemper OS is written in some incarnation of C++
Thanks
