If you look at the HTML page and then view the console, what does the JavaScript error say?  To view the console you can F12 and then press console or under the menu find the more tools (in chrome) > developer tools and press the console.  In Safari, you may have to turn your console on under preferences > advanced and show develop menu in menu bar.

your fla may be corrupted.

save with a new name in a new folder

restart your computer

reopen animate

create a test fla with nothing in it and test

if there are no problems, open your problematic fla from the new folder and test

same problem?

if so, try to repair by:

rename to a rar

repair with winrar

rename to a fla

try opening and testing the repaired fla

if that all fail, learn to save your fla's frequently with increasing version number appended and periodically close and reopen the latest version to ensure you're not working on a corrupted fla.
