Muse Score Drumline sounds not working

Hello,
Im not the most knowledgeable when it comes to muse score, but muse score drumline was working fine until recently, when it randomly just wouldn't play any audio any more. When I went to mixer and selected another sound, it always just sounds like a bongo and all the sounds from musescore drumline are gone. I would greatly appreciate it if someone could help me out. Thank you so much!
