UR44 problem

My ur44 worked just fine, and now it blinks and the computer won’t recognize it. Iv’e switched USB cables, tried connecting it to my laptop…nothing. I have windows 10 on my computer and windows 7 on my laptop. I looked in all the forums and couldn’t find an answer…
Thanks in advance.

Check the CC mode switch is in the correct position for pc use. You may have accidentally clicked it over.

Still-nothing. I also cant seem to contact steinberg directly.
