Make sure you go to your file>publish settings. Uncheck 'web' and check 'Animate Deployment Package.' Then click save. Then go back to file>publish. Should work. Good Luck.
It's possible you have an error in your file somewhere - do you get a warning in your composition? You should look for a little stop sign icon in the lower right hand side of the Stage window. You can click on it to get more information on your error if you have one. Otherwise, you should post your file for us to take a look at so that we can tell you what's going on.
THAT WORKED ! UN checking Web.
