As you just told, Irdeto cards were attacked in Turkey. We are not in Turkey, but if we have Irdeto card, it will be sublect to attack as well similar to those of NOVA (Irdeto) and Sky Italia (NDS). This so-called "fashion" becomes popular among satellite providers. It is aimed, first of all, against piracy. All cards of such type are being sold together with receivers. If we "unpair" the card (it means that we'll use our own receiver, but not the one which was sold together with the card), we also can suffer from attack. The card will be simply killed. They check if we use the card with the receiver "in pair" or "in couple". Clear?
I cannot recommend to wait until a new card arrives, because "the happiness" will not last long, sure.
Make your own decision in this case.
