Can you provide a link to your .fla in a no higher format than CS3?
Since you don't have enough posts to attach it here, you can upload your .fla, to a file sharing site as www.rapidshare.com
, or to some web space of your's, and then provide here the link to download it from. But since you can't really post links either, omit the http://www
part when posting it...
If you can't back save to a CS3 format, upload an outputed .swf and I'll attempt to decompile it in a CS3 format .fla.
