Articulate 13 cannot be upgraded
Can anyone advise me on this please?
I have just spent hours on a PowerPoint presentation, but when I click on the Articulate tab to add a quiz, I get this message below. I have looked at all my previous presentations and Articulate works OK on them. Its probably something very simple but I cant think what.
"Your Articulate Presenter project cannot be upgraded to the new Articulate Presenter '13 file format".
Thank you so much
