Possible fix for fatal error caused by Neospeech-generated items

Just thought I'd share a blunt force fix for a project that was generating one those "Adobe Captivate - A fatal error has occurred and the application is being terminated. Adobe Captivate has tried to save all your work in the respective project folder as .cpbackup files. Please restart Adobe Captivate." messages on a PC, and simply freezing the program on a Mac.

At some point a few days ago, when I selected a few particular slides in my Filmstrip, the program would freeze up. I tried all the standard things, deleting Preferences, Cache, etc., with no positive results. I couldn't select a slide to delete it. I'm using the Neospeech free voices, and started thinking that was the cause. But I couldn't delete either the audio file from the Properties > Option panel or from the timeline of the slide, nor could I access the menu Audio > Edit, nor could I select the audio files in the Library. All these attempts resulted in a freeze or fatal error.

I was finally able to delete the audio files from their respective slides using the Audio Management tool, and then delete the audio files from the Library using the Select Unused Items button. Maybe this will help someone down the road, too.
