I recently left someone to record audio for a PPT in Articulate. I believe they failed to 'save and close' once they finished, and it appears my computer ran out of battery. Upon restarting, I find that the ribbon has disappeared. This has happened before and I've simply been able to re-add the ribbon from the PPT add-ons. However, this is not working, and I can't figure out what to do to bring the ribbon back when I open PPT.
