Compiler errors but no AS in file / Please help!

Hi,

We use Adobe Animate CC for an animation project in the game design course that I teach every Fall semester. A student has been working very hard on her animation project, and she is now unable to export her files to MP4 format because she receives this bizarre compiler error.

The error message clearly indicates something is wrong in some sort of ActionScript file, but there is no ActionScript in her file at all. I have tried copying the project to a different folder and we encounter the same problems.

Does anyone have any suggestions? This type of error can be very demoralizing to students who are using the product for the first time.

Thanks!

Aaron
