I keep receiving the message above on a presentation I am working on. I've tried moving the file to a new folder, like Articulate suggests, to disassociate it with existing presenter files. But, there actually are no presenter files. It's like there is no Articulate, even though the Articulate ribbon is at the top of my presentation. I've opened just the template file I was working with (rather than the whole presentation) and the template gets the same error message. I've used the template I'm trying to work with for 4 different presentations recently with no issues. I can't even make and "Articulate Package" to send to Articulate for diagnosis, as they suggest, because there are no Articulate files. Any suggestions?
