Fail to publish with imported audio narration

Hi. I am currently using iSpring Presenter. I have tried on numerous occasions to publish a presentation which contains imported audio narration. Each time, I receive a fail message. I have tried a number of different audio formats (.wav, .wma, .mp3) and none seem to work.

I have uninstalled iSpring Presenter, and re-installed (thinking that perhaps there was a download issue). This has not fixed the problem.

I have tested publishing the same presentation without the imported audio narration, and it works fine. The problem seems to be only when an audio file is imported. I have also tested with other presentations just to make sure. I always end up with the same result.

Any ideas? Thanks!
