Cap7: Problems with Publishing .mp4 file on Mac

Hello,

Using Captivate 7 for the Mac, i imported a Power Point PPTX file, added audio tracks to the slides, and then tried to Publish it for YouTube. It did not work. After trying many different ways to publish, I realize that the published .mp4 file is zero bytes every time. I have tried all formats for you tube, as well as strait mp4. Those don't work. Publishing to html5 format works OK.

Hardward: Mac Book Pro Mid-2011

Mac OS: Lion

App: Captivate 7.0.0.118, I also updated Adobe Media Encoder 6.0.2.81

Anyone have any ideas?

Thanks,

Jeff
