Hello,
I'm also having problems with the export script.
Running AE CC 2015 on a Win7 machine. Whenever I run the script, an error occurs: "Script can not be executed in line 1251. Undefined is is not an object."
Any suggestions, what's could be the cause?
I know of someone, who has successfully used the export script on AE CC 2014 and my AE composition exports fine on his WIN machine.
EDIT: Alright, I found the problem. The script runs fine, once you have switched your AE to english. Living in Germany, it automatically installed as german version. Been googling for how to switch language and that little bit helped.
