i read somewhere that you have to reboot your computer and press a button (i believe f8) and disable driver signing. basically have to do this everytime you turn your computer on due to win-7 64-bit being a pain in the a$$ like that. go here for the drivers

EDIT: you have to manually install the drivers via device manager, as BH_MAN states in post 22.
