We have the same issue. Currently we have three people using
this program and all experience the same problem. My best advice is
to run the installer (which is saved in your computer) and run
that. If you republish after you run that, and you still have the
problem, run the installer again. Sometimes I have to run it three
or four times, but it will eventually work. I figured this out one
day bc I was tired of getting nothing from tech support. I have
called so much and never got an answer, plus I called all the
offices listed in the US, got no one, they just kept transferring
me to India. Their tech support and customer service are useless.
Try that, hopefully that should work. Also, if you start
getting audio that doubles (you hear the audio but the same audio
is playing along with it..almost like you put the same audio track
on a slide, two times), export the audio onto your desktop then
remove the audio on the slide, then import the audio that you just
exported back onto the slide. Sounds crazy, but that's the fix.
Hope that helps!
