Zoom H5 interface will not connect with Cubase

Can anyone help with this? I have completed several projects with this setup, so I know the basics, but all of a sudden, my zoom H5 will not connect to cubase LE 8.

Cut & paste from my tech support request which has not been answered:

Zoom H5 interface will not connect with Cubase. I have been using it with no problems until this problem appeared today on startup. Cubase came bundled with this device.
H5 interface driver is updated, re-installed and running properly.
H5 device still works correctly with other software (Audacity).
Cubase sees the zoom H5 ASIO driver and I can switch to the driver and configure it normally in Cubase Device Setup.
In Cubase VST Connections - Audio Device column says Not Connected for all inputs and outputs, all buses. I can left-click and H5 device is listed in pop-up menu but I cannot switch to it - will not connect. Device Port column shows Not Connected for all inputs and outputs and none of the H5 I/Os appear in the left-click pop up.
