Wow! Really? Where did you get Platforma n from? We do not offer this provider, only Polsat Cyfrowy and Cyfra+. If you mean the channels that were included into "N" earlier, they stopped working for everybody. Currently, new cards of NC+ package have been ordered and we are waiting for them to arrive. For information: Polsat Cyfrowy and Cyfra+ are on the way to merge, that is the reason why many channels stopped working.
