I’m running XP pro with service pack two. I wonder if the problem has something to do with I'm running at two partitions. The one with XP and MP that is E:\\. Then if the program just searches C:\\ it wouldn't find the card. I have tried to update the drivers and reinstall MP. The card works fine with Cinergy Home Cinema. I'm running the newest version of MP. But the card can’t be found by MP of some unknown reason. Thankful for all help I can get!
