Imported Sound doesn't work.

I know this problem has been posted before but I’ve yet to find a solution in previous posts. I’ve done about everything minus completely reinstalling Toonboom. I hope it won’t have to come to that.

At any rate, whenever I import a .wav or .aif file I get no sound. Even when I double click on the layer to bring up the Sound Element Editor, the sound doesn’t work in there either.

Any help would be greatly appreciated. I’m using Harmony Premium.
