Adobe released Adobe Flash Player 16 on December 9, 2014 and, as a result, Articulate products won’t open properly. Published content isn’t impacted.
We’re working fast and furiously to fix the issue, and will release updates as soon as humanly possible.
*UPDATE* The issue has been resolved for Storyline 2, Storyline 1 and Studio '13. Please upgrade to the latest version of Storyline 2, Storyline 1, or Studio '13 as appropriate. An update for Replay is available as well.
