MobilePre Academic Not Showing

So I have a 2012 MacBook Pro and my teacher let me borrow a MobilPre Academic until I get my Mbox Pro 3. I download the correct drivers (or so I think) and when I go to System Preferences and output nothing shows for a USB audio interface. Please help me, I just bought KRK Rokit 8's and I'm dying to listen to them. I'm running Mavericks.
