NASN keys Please

[slim56]

Can you please tell me if NASN is working on ASTRA 1?
I have a metabox with the last MTG10 firm which opens most premiere channels except the noname ones for movies but NASN & NASN(P) became encrypted about 10 days ago.

NASN is gone together with some other channels,after the partial
encryption change to Nagra 3.

But the arena.tv bouquet doesn't use the cryptoworks system? Canalsat seca?
Why is not possible to see it?
Thanks
