Cubase 6.0.7. and Komplete Kontrol S61 Crashes suddenly

Since a long time the NI Komplete Kontrol S61 MIDI keyboard has been working
nicely together with Cubase 6.0.7. and Komplete Kontrol VST.
However, recently Cubase crashes when starting up, just behind the message ‘initialising: retrospective recording’.
It is ONLY happening when the NI Komplete Kontroller is connected via USB and ON. I have no problem whatsoever with the other connected devices/keyboard controller.
Note: the drivers are all the most recent ones and Ableton has no problem whatsoever with it; everything is nicely installed.

it seems to be the same issue as reported for other Cubase versions and NI Komplete Kontrol S49

Can anybody provide a hint for a solution ?
