Can't Connect New Came 4 to Studio

[Neries]

I moved my Cameo 3 and unpacked my new Cameo 4 just after 2.pm this afternoon. No instructions with the machine it is all on line at Silhouette America. No way can I get Studio to recognise the Cameo 4.Turned off, unplugged machine and USB cable then rebooted computer about 3 or 4 times. I have gone through most of the trouble shooting on Silhouette America. Wasted over 4 hours and still not sorted. My computer running windows 10 knows the Cameo 4 is there but Studio does not. I have gone down the list to 'Interfering Connections' which says 'devise not migrated'.
