Hi,
It looks like Polsat Cyfrowy ended "Open Window" for some channels. It means, that card cannot decode them.
More information:http://satkurier.pl/news/86205/cp-koniec-otwartego-okna-tv-republika-i-13th-street.html. It concerns other channels as well. They have created different packages, therefore not all the channels are available in one package.
I hope it will help understand what is happening at present to avoid all unnecessary questions as well.
Kindest regards
