Audio Editor not saving

Hi everyone,

I have been working on a course and every time I shorten the slide using the Audio Editor and click Save and Close, my changes are lost. I have been reading the posts here and I saw there are two reasons this might be going on:

• The file is corrupt- this is not the case, since I created a new project, tested and I couldn't save my changes either.
• Disabled Add-Ins- not the case, all add-ins are enabled.

 

Any ideas on how I can fix this?

 

Thank you!
