Behringer usb audio driver freezing cubase 8

Each time I enter the ASIO setting dialogue box for the (2902) Behringer ASIO driver Cubase freezes and I have to use Ctrl/Alt/Del to get out and restart the app.
I think this may be a Win 10 issue (because I went back to Win 8 and the problem did not manifest). It worked with Win 10 in the past so it must be a recent update.
Anyone had any similar problems?
very grateful. Dennis
