Problem getting MR816x to record

Well…still have a problem with getting an audio signal from the MR816 to Cubase. Can anyone offer anything. I tried contacting Steinberg Tech Support by e-mail (several) but no response. Cubase AI is installed and seems to be functional. I’ve verified that the assigned driver is the Yamaha Steinberg FW ASIO. The inputs all seem to be assigned. Signal does go from the mic to the interface. No fader level activity in Cubase. Does anyone know of a telephone # to contact Steinberg. ANY advice would be appreciated.
For contact.

Did you receive an email verfication that your mail was sent to support?

Could you make a screen of the menu you get with F4 inputs outputs.
