First make sure that the sound card is plugged into the PCI slot on your motherboard, then make sure you have the drive bay installed inside your computer alongside your CD/DVD drives. Then make sure you hook up the IDE cable from the front box to the sound card, and also hook up the floppy power connector to the front box. Then make sure the batteries are installed in the remote, and point the remote at the front drive panel.
The software/drivers also have to be correctly installed for it to work.
