Missing Audiodriver after Update to Vers.

After Update from VST Live pro 1.0.10.xxx to Vers. Software shows “Missing ?”
VST Live

Same to My Presonus StudioLive III 64S. USB Audio Driver is not available.

You need to change your audio device to Yamaha USB, either in hub, or Devices/Audio Device, then load project again.

Thank you very much for the hint.
Now I see again all USB channels of the Yamaha 01V96i and those of my Presonus StudioLive III 64S… Why didn’t I come up with it myself?
