"Adobe Media player failed to encode, please check the status in Adobe Media encoder queue..."

thanks

I've tried both ways. Same thing. 

however, I have now discovered that if I create a new animate file and export, it works, I can even make changes and re export and it works, but when I save the animate file, the export stops working

i can't export any animates file that has been saved, only new files before they have been saved

my file is a full had animation at 30 fps and I've tried both action script 3 and html 5 and get the same problem
