Are you sure that you really need a new card? I've got my doubts! I'll try to explain them:
There are two types of 'free' satellite channels. 'Free to air' (FTA) channels are unencrypted and can be received by ANY satellite receiver. 'Free to view' (FTV) channels are encrypted. You don't need a subscription to view them but you do need a valid viewing card.
At one time many free channels were 'FTV' so, in order to get the full range of channels you needed a valid viewing card. Gradually, nearly all channels switched to 'FTA', leaving only the 'Five' group in the 'FTV' format. So the only point of having a viewing card was to be able to watch 'Five', 'Fiver', etc.
However 'Five' turned off its encryption, and started broadcasting 'in the clear', 17 months ago. (i.e. it changed from 'FTV' to 'FTA'). So you should now no longer need a viewing card to watch any of the free channels.
Try taking the card out of the box. You might well find that you can still get all channels and (because there's no longer an 'out of date' card in the box) not see that annoying message.
