SeeMusic Not Acknowledging Sustain Pedal

I am using a Yamaha DGX 650, and have connected it to my desktop. It is detecting all keypresses but is not detecting my sustain pedal. I use a physical sustain pedal, and its completely functional on the keyboard itself but does not make any change in sound on SeeMusic. I am on the latest version, this is my first time using the software, and who knows maybe I just need to download some kind of software or enable some setting Thanks for your help!
