TBS6982 installation problem

Hello
I've just received TBS6982 DVB-S2 Dual Tuner PCIe Card. I experienced problem during card installation and configuration. Driver installation went ok, but problem was when I launched BlindScan I figured out that my system "sees" only one tuner (tuner B). I also tried new Windows 7 installation, but it didn’t help. I don’t know if I do something wrong or this card is faulty. Maybe Win 7 driver is not fully operational ? Do you have any clue ?
Here are my system components :
Asus P8P67 PRO motherboard
Intel i5 2500K processor
MSI GTX 460 graphic Card
OS:
Windows 7 Ultimate 32 bit
Regards
