My Flamewheel looks good, ready to set parameters. It powers up, connects to Tryanis Xmitter.  Connect to USB turns LED from flashing yellow to solid green.  But cannot get the Assistant to connect.  I have Windows 10 (up to date).  Suspect it is the "unsigned driver" problem, but I borrowed a work PC that is Windows 7 and it seems to have same or worse problem. HELP!
When I bring up the Assistant program it never gets off the splash screen unless I click on "skip".
Any help is appreciated.
Thanks,

Oh, I have NAZA M V2 with GPS

It was indeed the "unsigned driver" issue.  And after that I had a problem that the s-bus was not connected properly to the receiver.
