W8.1 and MOTU MicroLite

I have attempted several things:

Using a 2.0 Usb port
Using a 3.0 Usb port
Installed the oldest driver
Installed the newest driver
Swapped usb cables

I’m just not sure what to do next. The PC recognizes the unit. It is Nuendo that is not registering that the MicroLite is installed. Please help…anyone.
