Also, please try to add your project location to Flash Global settings and see if that helps.
In order to do that please go to Control Panel and double click Flash player then click Advanced at the top and then choose Trusted Location settings and click Add and select the folder which contains your published project files.
Hope this helps!
Thanks and Regards
