insert sound

Good Morning,

So since the last update, Story 1, I'm having problems when it comes to inserting sounds. I look at the screen, I click insert sound and try to import the audio of application but I never get to do it (the import dialog box closes and the audio never shows up in the timeline).
I always work with the same configuration of audio, mp3 recorded in professional studio, and so far I have not had any problems.
Can anyone help me out?
Thank you,
