no playback sound in cubase le with zoom r8

It was perfect just some time ago. Now there is no playback. What do I do? it’s a zoom r8 running cubase ai 9…

stereo outputs and inputs reads missing…the zoom r8 plays youtube music just fine…yet cubase doesn’t seem to recognize it…tried installing asio4all…44.1kz…the message once also read vst-synch disabled due to too much receiver errors…i had sound earlier today…and i didnt adjust any settings…maybe someone knows who did what, why and when or how to make the cubase 9 le work again…
