Old .fla project file plays in the scene timeline, but not in in browser when testing

Hi!

A published html interactive I created with Animate cc in 2016 is no longer working in the server and i am trying to figure out how to restore the project and get it up and running again.

Here is the link to the live version:

I managed to track down a source project file, and open it with the latest version of Animate cc. When I try to test it from the project to the browser, I get this error message and nothing launches:

WARNINGS:
Frame numbers in EaselJS start at 0 instead of 1. For example, this affects gotoAndStop and gotoAndPlay calls. (254) Modifying the transform point in a tween can produce unexpected results. (18) Shadow and glow filters are very expensive effects, and not all options are supported. (3) Content with both Bitmaps and Buttons may generate local security errors in some browsers if run from the local file system.

I am not sure how to make fixes with this message and could use some help. Been struggling with my troubleshooting efforts to no avail...Any help would be greatly appreciated!

Thank you,
Lauren
