Komplete Kontrol S61 MK2 became not recognized

Last week I have used the komplete kontrol functionality - I have many NKS products.

Today I realized that when I turn the S61 MK2 keyboard on, its screen only shows Komplete Kontrol - Smart keyboard kontroller.

Starting the standalone komplete kontrol software nothing happens - I can't use the keyboard, the screen only shows the above mentioned text.

On the other hand, when I load the DAW Reaper and load instruments (not in Komplete Kontrol) and press keys on S61 MK2, I still can play instruments....

My environment: windows 10, Komplete Kontrol 2.7.2 (R2) Full, I have Komplete 12 bundle.

Don't know what to do.... I thought maybe the USB cable is wrong ....
