Opening Presenter '13 or '09 in Presenter 360
I'm surprised I couldn't find this in a search, but I was unsuccessful. I was wondering if you can open Presenter '13 or '09 files in Presenter 360? (I have the trial version) I've tried but have not been able to open them. Admittedly, I'm a Storyline user, so maybe I'm missing something. But we have .ppta Presenter files (both '13 and '09) I'd like to be able to open in Presenter 360, but I don't seem to be able to do it. FYI, I'm using Office 2013.
What am I missing? Thanks for your input.
