Animate not exporting my animation to AME no queue

Unable to export to video.  I selected File/export to video for my short animation  on Animate cc; clicked on dialogue of how much of my animation to export and selected export at bottom .  Nothing happened after that.  Since AME was not opened ,I searched and opened my AME/ media encoder and went through the above process again.  I selected export from the prompt.   I've waited 20 minutes and there's nothing on queue in AME.  No dialogue from Animate if there's a problem.  What's going on and how can I export to video?
