BackupExec 2014 and Dell Pawervault 124t VS160 Media Changer Not in Device Manger

I have recently installed BackupExec 2014 on a Windows Server 2012 box.  I have a Dell Powervault 124t VS160 SCSI Tape vault attached to the box.  The drive itself is recognized fine but the media changer is not showing up in the device maager.  If I manually put a tape in the drive, my backup will run until the media is full.  However, my problem is that without the media changer (autoloader) installed, BE will not automatically change tapes.  Does anyone have any ideas on why the media changer is not showing up in the device manager?  I did not have this problem with Server 2008 and BackupExec 2012.  PLEASE HELP!!!
