Help with soundcard

Can someone help me with the settings on a 24/96 please?
I just switched over to Windows 7 from XP. The soundcard settings seem to be quite different than that of XP.
I can hear the music that I am playing back after recording (I use N-Track recoding software).
However,
When I begin another “Track”, I can not hear what I am playing/singing at the same time. (monitoring)

I’m sure it is just a matter of getting all the settings just right in the sound card.
The tabs in the soundcard settings window are: “MIXER”—“INPUT”—“OUTPUT”—“HARDWARE”—"ABOUT"

Thank you for your help !!!
