ERROR: Sorry - i couldn't get any working frequency/transponder Nothing to scan!

hi,

I am having troubles with this dvb-t usb stick: http://www.conceptronic.net/es/download_list.php?stype=1&back=2&productid=291

On windows 10 on another computer it works perfectly, but I cannot manage to work in raspberry pi 2 model B.

The usb stick is recognised and I can scan frequencies with w_scan command, but I am getting the error mentioned in the topic.

The tutorial im following is this one:

In my case kernel version is 4.1.5-1-osmc.

Could someone help me please? I am desperated. I will answer your questions immediately because I need to solve this problem.

Many thanks
