DVBT sticks (2!) not working - devices written in red

#1
Hi,

I would like to use a DVBT stick on my laptop. My tried to install "Pinnacle teleScope" and "MSI Digi vox mini II" but both are not working with Prog DVB. I downloaded the drivers from the official pages and I am running Win 7 64-bit. When I open the TV sources settings in Prog DVB and enable either of the devices, they are written in red and when I close the windows it says that additional settings have to be made. But I have no idea what that means.
I also tried other DVB programs and they are also not working.
Does anybody have an idea of what I am doing wrong? Please help me ;)

Thanks
