Midi Keyboard isn't being recongnized by Musescore

Hello,

I have an AKAI MPKmini keyboard, but Musescore doesn't seem to recognize it. Has anyone else had this problem? I go into preferences --> I/O but when I click PortAudio, there are no recognizable devices listed. My computer does recognize the keyboard in other programs such as hydrogen and Ardour, just not Musescore. Any help would be appreciated, thanks!
