I accidently tried to transfer a file from Pc to the kn7000 when the kn7000 was not in the home screen. So I got an error message.
I put the kn7000 on the home page and I still got the error message.
I restarted the kn7000 , the pc always the same message.
I reinstalled the usb driver and the applications and still not possible to tranfer to the kn7000.
What is wrong now ??
