I have a fair amount experience in coding. I started working with my Edge Animate CC today. I have worked it in the past, not too far or difficult tasks, but today I have spent three hours trying to resolve this issue and finally came to the conclusion that something is very wrong. I create some stuff on stage and went down to the simpliest task (mimicing Lynda.com instructions to the letter) and I could not even get the Playhead to STOP. I had some stuff on stage and at 2 seconds did a Trigger and a Simple Stop.. Launch Browser and No Luck the only code was to stop at the 2 seconds... and it did not stop and played through. I did the Center to the Stage code and tested and it did not center in the browser... Nothing and not even the simpliest Code or Task are working... Please help!!!!!
Sounds like you may have had a "Hiccup" in the install... I have heard of similar things happening due to that, id try a reinstall and if that doesn't work contact adobe support directly, because that has to be an isolated thing.
