Tascam us16x8 problem with Cubase

I am wondering if anyone has had problems with tascam interfaces and functionality with cubase 9 pro after the windows spring update. I have a us-16x8 that was working great before the update and now is causing a major lag time in the functionality of the software to the point of it being unusable. My ur22 works great after updating the dirver and elicenser but tascam says there should be no problems. Just trying to find a direction to possible paths of solutions. Thanks to anyone out there with some insight.
