I returned my copy yesterday. Then I finally got a response from support and they recommended the following:

Recreate preferences of CS4 ::

Flash CS4 on OS X
1. Quit Flash CS4
2. Navigate to Users:USER:Library:application support:adobe:Flash CS4:en
3. Rename the Configuration Folder to “Configuration old”.
4. Navigate to Users:USER:Libraryreferences:
5. Trash the "Flash CS4 preferences" file.

Or to try a different CS3 file (did that), or reinstall Flash CS4 and directed me to this link: http://www.adobe.com/go/kb405535

I didn't try to recreate preferences or reinstall because I honestly don't have time to beta test for Adobe.
