hi I am experiencing weird problem with my project files, the entire project was created in Vista using CS3 but now this project is being edited in OS X CS3 and for some reason OS X has a hard time importing mc\_tween.as

```auto
 Error opening include file mc_tween2.as: File not found.

```

but no problem in Vista what do I do, what do I do
