I have a new computer, windows 8, with PowerPoint 2013. I recently downloaded Articulate Presenter and when I try to enable the Articulate ribbon it tells me that it is unable to load the Articulate Presenter add-in. When I go to the Articulate help, it shows how to resolve the issue for PPT 2010, but not 2013. Are others using Presenter with PPT 2013? Have you had problems like this that you have solved? Any help would be appreciated.
