Hi henno,
I shouldn't think that support for this card has finished yet, as this is a relatively new card and still selling, but providers obviously don't want you too view their channels for free, and so will do all they can to stop these cards working.
The last D+ file was unusual as the keys were public before a file appeared, not surprisingly they didn't last 24 hours.
Hopefully there will be some new files soon, otherwise I don't think many people will buy cards, for some time, and the suppliers will be stuck with a lot of useless merchandise.
Best wishes
Mickha
