PLEASE HELP. ANYONE. Phantom PPTA file left over from abortive attend to use Presenter 360
Long story short. I spent a day with the new Presenter 360 upgrading my Presenter file.
The next day I figured out the hard way that Presenter 360 doesn't support some Powerpoint functionality and my program was rendered useless.
I uninstalled 360 and went back to the latest '13 build.
Now I'm back in my 200+ slide training program and the Powerpoint functionality I lost is back HOWEVER I cannot add back in my audio files because even after deleting the associated ppta file I still get an error saying the ppta was "created with the newer version". See attached error message. I have completely uninstalled the new version and my .pptx file works fine -- but without any sound files because I cannot attach them because I've enountered this error.
I have done the following:
(1) Deleted the ppta file. Doesn't work -- it deletes, and creates a new one but still gives me this error message.
(2) Save under a different name... still the same issue.
