Friend of mine gave me his tv tuner card

Asus LNA tiger hybrid..from a HP m7585 p.c ....it was working perfect on his system...he has upgraded to twin tuner.

I have installed the correct driver ,version 13.3.1.7 from hp site...it's the same one as the HP states on device manager.

Device manager on my setup states all is ok /card is recognised etc....however....

When I go into Media Center/tv setup/scan channels....I get the error message saying there is no hardware tv tuner or no hardware driver....??

What am I doing wrong...

How can I fix this...?

Help appreciated...Thanks.
