No sound output

So I was trying to put in the Drumline soundfront that everyone uses, and that didn't work, I don't know why, but know every time I try to open musescore 2 and play something, know sound comes out. I have tried removing the soundfront, going into the synthesizer, reinstalling musescore, nothing worked. Even after musescore 2.0.2 came out, no music plays from there. Please help because I need to use musescore and I can't edit with know sound. Thanks.
