Director Cross Platform Issue

Hi,

I have done updates on a full interactive CD-Rom in Macromedia Director MX2004, and everything was working perfectly on both platforms (publishing from windows PC).

Now all I have done is update all the externally linked video files and tried to publish again for both platforms. The windows version still works perfectly, but now when I try play the .osx version for mac on a mac it comes up with an error saying “unable to read the dictionary of the application or extension because it is not scriptable.”

I am using an mpeg advance xtra for the CD-Rom.

Is there any simple setting that I am missing in the publishing or something?

Anybodies help will be greatly appreciated.
