Problems with TV (valid business license) started a week or so ago. Windows 10 Home. Now it continually puts up an intrusive popup message that it is running in limited demonstration mode. I am unable to enter an email or password to log in, as these boxes won't accept input. I am not using a network proxy. The system was running fine for the last 16 months. I have reinstalled TV without changing the results. My only system change was upgrading to a larger system disk drive by cloning. How do I get this running again?
