HI ...
What card you have.
When its seca its possible working.
If its Nagra3 you need to do more things.
For Nagra you need to read the box and rsa key, and thats not possible by your self and you need to send him to spain or to portugal or poland.
There are a few people that can read the keys from the orginal box that Digital+ give you with the card.
I can give you adres in spain, and for 120 euro they can do this.
send me PM if you like more info.
