CS3 classes not found/working

Hi -

I recently installed CS3. Now, whenever I add actionscript it won’t work, unless I open a new movie file and tell it to use Actionscript 2.0.

For example, using Actionscript 3.0, it won’t even recognize the loadmovie() function. The following code (cut and pasted from the help menu into the first frame of a blank movie) won’t work . . .

// Creates a movie clip to hold the container.
this.createEmptyMovieClip(“image_mc”, 9);
// Loads an image into image_mc.
image_mc.loadMovie(“http://www.helpexamples.com/flash/images/image1.jpg”);

It works fine if I choose Actionscript 2.0.

Also, if I try to export a movieclip “for use with Actionscript” - I get a warning about " A definition for this class cannot be found in the classpath, so one will be automatically generated in the SWF file upon export."

So obviously this is a problem with the path to the class files, but I dont understand why, if I accepted the defaults during installation, it can’t find the class library, and why, when you look for information how to fix this, you can never find it anywhere!
I even uninstalled and reinstalled Flash hoping it would restore the settings but it didn’t.

Sorry for whining. . . . can someone just tell me how to fix this before I waste more countless hours searching for answers?

Thanks
