OK I have solved my own problem.
Luckily I found a backup of my old Activation File from when I first installed
Window Eyes version 8 a couple of years ago.
I tried running this again, it activated online and Window Eyes has suddenly
decided it does not need to be in demo mode.
Interstingly it appears to be working better in Windows 10 Mail than Jaws 18
at the moment For example Jaws is not reading suggested auto complete email
addresses when you type in the To box but Window-Eyes is picking this up fine.
