Audio plays twice

jjs

I'm creating in Lectora v. 9 SP1, and when I'm working with several audio files (MP3) for each screen. All was going well until I reached audio file #29. When I play the slide with this audio file inserted, the audio file repeats itself once, that is to say that audio file #29 plays twice before advancing to audio file #30, which also plays twice. I haven't had this problem before, and I just updated my Lectora software today, so I'm wondering if it has something to do with the update? Any ideas?I'm creating in Lectora v. 9 SP1, and when I'm working with several audio files (MP3) for each screen. All was going well until I reached audio file #29.
