It works now, but I don’t know what I did. I tried plugging it into several usb ports, rebooting pc several times… I don’t know what exactly was the cause that it started working again. I guess dongle is dying or something…
One thing to note is, that I received no reply from Steinberg team to my problem, even after several weeks. Tried to call service in Germany by phone several times, but got no connection. I was hoping that somebody from Steinberg in this official forum would at least say something, give me an email or phone number of anybody from their service department… nothing! Really bad customer experience. Dissapointed.
that’s odd that they didn’t respond to you. I actually got response from the folks at Yamaha in the US as well as someone from Germany. What I did was to open a service request and they responded within 24 hours. Anyway, my problem is now resolved as well. Cheers!
