TNT SAT/ receiver not configured properly/ channels still encrypted

About 6-8 years I got tnt sat , sagem model ISD91 HD. I haven't used it
for about a year but I received a new replacement tnt sat card recently.
The reception from the dish is still fine but after turning it with the the new card the box is telling me that it is not "configured" properly and so channels like TFI/M6 etc are not available. Now some channels are viewable but as I only switched it on today I am wondering if an automatic upgrade will take place and sort this out , or is the the receiver even at this stage out dated. I did a channel search but the result was the same. If the channels are still encrypted is there anything that can be done to make them available. Any help / advice/ information would be much appreciated. db
