Please help mates

My question is that how I can ART sport channels/Aljazeera sport channels for free
, because my ART 3 month subscription ended today and I haven't enought money to by a new subscription card (because I'm student)

I would be thankful if somebody tells me a simply step by step-tutorial, about how to use these activate keys.

I live in Finland so I'm under the Hotbird coverage area.

My receiver is Starsat Sr-x3100 cu ultra, and I haven't download any software on it or updated.

Please somebody help me
