I have purchased a Newmi DM22S USB2.0 DVB-S TV Box (http://www.newmi.com/en/productsshow.asp?id=572).

I have installed the driver and ProgDVB successfully and it was working fine.
One time, ProgDVB got stuck, I had to unplug the DVB USB Box from the computer. After this incident, I get an error message every time ProgDVB starts: "Device not started". Even reinstalling the driver and other versions of ProgDVB does not help.

Is the USB Box faulty? Is anyone aware of this problem?

You must check Settings->Device list.
Do you have BDA driver?

Hi.
