Help! My audio is working when I use scrubbing, but not when I'm playing the audio back

I haven’t used ToonBoom in a couple of years and repurchased the newest version of it.
I imported an Mp3 file for my part of an animation map, and the sound isn’t working.
But when I used scrubbing the sound was working fine.
I tried playing it back again but the sound won’t work.
Can anyone help me out with this?
