hey all, i'm using sibelius 5.2.5 and have a strange problem when playing on any instruments. it occurs when openning the instruments dialog and then, selecting any instrument from this and adding this to the score. when playing in the querty keyboard it doesn't play any sound. this occurs when playing in the midi keyboard also. how can i fix this?, it doesn't let me know what i'm doing. thanks for advance!
